|
+ASoC currently supports the three main Digital Audio Interfaces (DAI) found on
|
|
+SoC controllers and portable audio CODECS today, namely AC97, I2S and PCM.
|
|
+
|
|
+
|
|
+AC97
|
|
+====
|
|
+
|
|
+ AC97 is a five wire interface commonly found on many PC sound cards. It is
|
|
+now also popular in many portable devices. This DAI has a reset line and time
|
|
+multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines.
|
|
+The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
|
|
+frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97
|
|
+frame is 21uS long and is divided into 13 time slots.
|
|
+
|
|
+The AC97 specification can be found at :-
|
|
+http://www.intel.com/design/chipsets/audio/ac97_r23.pdf
|
|
+
|
|
+
|
|
+I2S
|
|
+===
|
|
+
|
|
+ I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and
|
|
+Rx lines are used for audio transmision, whilst the bit clock (BCLK) and
|
|
+left/right clock (LRC) synchronise the link. I2S is flexible in that either the
|
|
+controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
|
|
+usually varies depending on the sample rate and the master system clock
|
|
+(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate
|
|
+ADC and DAC LRCLK's, this allows for similtanious capture and playback at
|
|
+different sample rates.
|
|
+
|
|
+I2S has several different operating modes:-
|
|
+
|
|
+ o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC
|
|
+ transition.
|
|
+
|
|
+ o Left Justified - MSB is transmitted on transition of LRC.
|
|
+
|
|
+ o Right Justified - MSB is transmitted sample size BCLK's before LRC
|
|
+ transition.
|
|
+
|
|
+PCM
|
|
+===
|
|
+
|
|
+PCM is another 4 wire interface, very similar to I2S, that can support a more
|
|
+flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
|
|
+to synchronise the link whilst the Tx and Rx lines are used to transmit and
|
|
+receive the audio data. Bit clock usually varies depending on sample rate
|
|
+whilst sync runs at the sample rate. PCM also supports Time Division
|
|
+Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This
|
|
+is sometimes referred to as network mode).
|
|
+
|
|
+Common PCM operating modes:-
|
|
+
|
|
+ o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
|
|
+
|
|
+ o Mode B - MSB is transmitted on rising edge of FRAME/SYNC.
|
|
+
|
|

|
|
+ASoC DAI Configuration
|
|
+======================
|
|
+
|
|
+Every CODEC DAI and SoC DAI must have their capabilities defined in order to
|
|
+be configured together at runtime when the audio and clocking parameters are
|
|
+known. This is achieved by creating an array of struct snd_soc_hw_mode in the
|
|
+the CODEC and SoC interface drivers. Each element in the array describes a DAI
|
|
+mode and each mode is usually based upon the DAI system clock to sample rate
|
|
+ratio (FS).
|
|
+
|
|
+i.e. 48k sample rate @ 256 FS = sytem clock of 12.288 MHz
|
|
+ 48000 * 256 = 12288000
|
|
+
|
|
+The CPU and Codec DAI modes are then ANDed together at runtime to determine the
|
|
+rutime DAI configuration for both the Codec and CPU.
|
|
+
|
|
+When creating a new codec or SoC DAI it's probably best to start of with a few
|
|
+sample rates first and then test your interface.
|
|
+
|
|
+struct snd_soc_dai_mode is defined (in soc.h) as:-
|
|
+
|
|
+/* SoC DAI mode */
|
|
+struct snd_soc_dai_mode {
|
|
+ u16 fmt; /* SND_SOC_DAIFMT_* */
|
|
+ u16 tdm; /* SND_SOC_HWTDM_* */
|
|
+ u64 pcmfmt; /* SNDRV_PCM_FMTBIT_* */
|
|
+ u16 pcmrate; /* SND_SOC_HWRATE_* */
|
|
+ u16 pcmdir:2; /* SND_SOC_HWDIR_* */
|
|
+ u16 flags:8; /* hw flags */
|
|
+ u16 fs; /* mclk to rate divider */
|
|
+ u64 bfs; /* mclk to bclk dividers */
|
|
+ unsigned long priv; /* private mode data */
|
|
+};
|
|
+
|
|
+fmt:
|
|
+----
|
|
+This field defines the DAI mode hardware format (e.g. I2S settings) and
|
|
+supports the following settings:-
|
|
+
|
|
+ 1) hardware DAI formats
|
|
+
|
|
+#define SND_SOC_DAIFMT_I2S (1 << 0) /* I2S mode */
|
|
+#define SND_SOC_DAIFMT_RIGHT_J (1 << 1) /* Right justified mode */
|
|
+#define SND_SOC_DAIFMT_LEFT_J (1 << 2) /* Left Justified mode */

+#define SND_SOC_DAIFMT_DSP_B (1 << 4) /* L data msb during FRM */
|
|
+#define SND_SOC_DAIFMT_AC97 (1 << 5) /* AC97 */
|
|
+
|
|
+ 2) hw DAI signal inversions
|
|
+
|
|
+#define SND_SOC_DAIFMT_NB_NF (1 << 8) /* normal bit clock + frame */
|
|
+#define SND_SOC_DAIFMT_NB_IF (1 << 9) /* normal bclk + inv frm */
|

|
|
+#define SND_SOC_DAIFMT_IB_IF (1 << 11) /* invert bclk + frm */
|
|
+
|
|
+ 3) hw clock masters
|
|
+ This is wrt the codec, the inverse is true for the interface
|
|
+ i.e. if the codec is clk and frm master then the interface is
|
|
+ clk and frame slave.
|
|
+
|
|
+#define SND_SOC_DAIFMT_CBM_CFM (1 << 12) /* codec clk & frm master */
|
|
+#define SND_SOC_DAIFMT_CBS_CFM (1 << 13) /* codec clk slave & frm master */
|
|
+#define SND_SOC_DAIFMT_CBM_CFS (1 << 14) /* codec clk master & frame slave */
|
|
+#define SND_SOC_DAIFMT_CBS_CFS (1 << 15) /* codec clk & frm slave */
|
|
+
|
|
+At least one option from each section must be selected. Multiple selections are
|
|
+also supported e.g.
|
|
+
|
|
+ .fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_LEFT_J | SND_SOC_DAIFMT_RIGHT_J | \
|
|
+ SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_NB_IF | SND_SOC_DAIFMT_IB_NF | \
|
|
+ SND_SOC_DAIFMT_IB_IF
|
|
+
|
|
+
|
|
+tdm:
|
|
+------
|
|
+This field defines the Time Division Multiplexing left and right word
|
|
+positions for the DAI mode if applicable. Set to SND_SOC_DAITDM_LRDW(0,0) for
|
|
+no TDM.
|
|
+
|
|
+
|
|
+pcmfmt:
|
|
+---------
|
|
+The hardware PCM format. This describes the PCM formats supported by the DAI
|
|
+mode e.g.
|
|
+
|
|
+ .pcmfmt = SNDRV_PCM_FORMAT_S16_LE | SNDRV_PCM_FORMAT_S20_3LE | \
|
|
+ SNDRV_PCM_FORMAT_S24_3LE
|
|
+
|
|
+pcmrate:
|
|
+----------
|
|
+The PCM sample rates supported by the DAI mode. e.g.
|
|
+
|
|
+ .pcmrate = SNDRV_PCM_RATE_8000 | SNDRV_PCM_RATE_11025 | SNDRV_PCM_RATE_16000 | \
|
|
+ SNDRV_PCM_RATE_22050 | SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \
|
|
+ SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000
|
|
+
|
|
+
|
|
+pcmdir:
|
|
+---------
|
|
+The stream directions supported by this mode. e.g. playback and capture
|
|
+
|
|
+
|
|
+flags:
|
|
+--------
|
|
+The DAI hardware flags supported by the mode.
|
|
+
|
|
+/* use bfs mclk divider mode (BCLK = MCLK / x) */
|
|
+#define SND_SOC_DAI_BFS_DIV 0x1
|
|
+/* use bfs rate mulitplier (BCLK = RATE * x)*/
|
|
+#define SND_SOC_DAI_BFS_RATE 0x2
|
|
+/* use bfs rcw multiplier (BCLK = RATE * CHN * WORD SIZE) */
|
|
+#define SND_SOC_DAI_BFS_RCW 0x4
|
|
+/* capture and playback can use different clocks */
|
|
+#define SND_SOC_DAI_ASYNC 0x8
|
|
+
|
|
+NOTE: Bitclock division and mulitiplication modes can be safely matched by the
|
|
+core logic.
|
|
+
|
|
+
|
|
+fs:
|
|
+-----
|
|
+The FS supported by this DAI mode FS is the ratio between the system clock and
|
|
+the sample rate. See above
|
|
+
|
|
+bfs:
|
|
+------
|
|
+BFS is the ratio of BCLK to MCLK or the ratio of BCLK to sample rate (this
|
|
+depends on the codec or CPU DAI).
|
|
+
|
|
+The BFS supported by the DAI mode. This can either be the ratio between the
|
|
+bitclock (BCLK) and the sample rate OR the ratio between the system clock and
|
|
+the sample rate. Depends on the flags above.
|
|
+
|
|
+priv:
|
|
+-----
|
|
+private codec mode data.
|
|
+
|
|
+
|
|
+
|
|
+Examples
|
|
+========
|
|
+
|
|
+Note that Codec DAI and CPU DAI examples are interchangeable in these examples
|
|
+as long as the bus master is reversed. i.e.
|
|
+
|
|
+ SND_SOC_DAIFMT_CBM_CFM would become SND_SOC_DAIFMT_CBS_CFS
|
|
+ and vice versa.
|
|
+
|
|
+This applies to all SND_SOC_DAIFMT_CB*_CF*.
|

|
+
|
|
+Simple codec that only runs at 8k & 48k @ 256FS in master mode, can generate a

|
+Audio Clocking
|
|
+==============
|
|
+
|
|
+This text describes the audio clocking terms in ASoC and digital audio in
|
|
+general. Note: Audio clocking can be complex !
|
|
+
|
|
+
|
|
+Master Clock
|
|
+------------
|
|
+
|
|
+Every audio subsystem is driven by a master clock (sometimes refered to as MCLK
|
|
+or SYSCLK). This audio master clock can be derived from a number of sources
|
|
+(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
|
|
+audio playback and capture sample rates.
|
|
+
|
|
+Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that
|
|
+their speed can be altered by software (depending on the system use and to save
|
|
+power). Other master clocks are fixed at at set frequency (i.e. crystals).
|
|
+
|
|
+
|
|
+DAI Clocks
|
|
+----------
|
|
+The Digital Audio Interface is usually driven by a Bit Clock (often referred to
|
|
+as BCLK). This clock is used to drive the digital audio data across the link
|
|
+between the codec and CPU.
|
|
+
|
|
+The DAI also has a frame clock to signal the start of each audio frame. This
|
|
+clock is sometimes referred to as LRC (left right clock) or FRAME. This clock
|
|
+runs at exactly the sample rate (LRC = Rate).
|
|
+
|
|
+Bit Clock can be generated as follows:-
|
|
+
|
|
+BCLK = MCLK / x
|
|
+
|
|
+ or
|
|
+
|
|
+BCLK = LRC * x
|
|
+
|
|
+ or
|
|
+
|
|
+BCLK = LRC * Channels * Word Size
|
|
+
|
|
+This relationship depends on the codec or SoC CPU in particular. ASoC can quite
|
|
+easily match BCLK generated by division (SND_SOC_DAI_BFS_DIV) with BCLK by
|
|
+multiplication (SND_SOC_DAI_BFS_RATE) or BCLK generated by
|
|
+Rate * Channels * Word size (RCW or SND_SOC_DAI_BFS_RCW).
|
|
+
|
|
+
|
|
+ASoC Clocking
|
|
+-------------
|
|
+
|
|
+The ASoC core determines the clocking for each particular configuration at
|
|
+runtime. This is to allow for dynamic audio clocking wereby the audio clock is
|
|
+variable and depends on the system state or device usage scenario. i.e. a voice
|
|
+call requires slower clocks (and hence less power) than MP3 playback.
|
|
+
|
|
+ASoC will call the config_sysclock() function for the target machine during the
|
|
+audio parameters configuration. The function is responsible for then clocking
|
|
+the machine audio subsytem and returning the audio clock speed to the core.
|
|
+This function should also call the codec and cpu DAI clock_config() functions
|
|
+to configure their respective internal clocking if required.
|
|
+
|
|
+
|
|
+ASoC Clocking Control Flow
|
|
+--------------------------
|
|
+
|
|
+The ASoC core will call the machine drivers config_sysclock() when most of the
|
|
+DAI capabilities are known. The machine driver is then responsible for calling
|
|
+the codec and/or CPU DAI drivers with the selected capabilities and the current
|
|
+MCLK. Note that the machine driver is also resonsible for setting the MCLK (and
|
|
+enabling it).
|
|
+
|
|
+ (1) Match Codec and CPU DAI capabilities. At this point we have
|
|
+ matched the majority of the DAI fields and now need to make sure this
|
|
+ mode is currently clockable.
|
|
+
|
|
+ (2) machine->config_sysclk() is now called with the matched DAI FS, sample
|
|
+ rate and BCLK master. This function then gets/sets the current audio
|
|
+ clock (depening on usage) and calls the codec and CPUI DAI drivers with
|
|
+ the FS, rate, BCLK master and MCLK.
|
|
+
|
|
+ (3) Codec/CPU DAI config_sysclock(). This function checks that the FS, rate,
|
|
+ BCLK master and MCLK are acceptable for the codec or CPU DAI. It also
|
|
+ sets the DAI internal state to work with said clocks.
|
|
+
|
|
+The config_sysclk() functions for CPU, codec and machine should return the MCLK
|
|
+on success and 0 on failure.
|
|
+
|
|
+
|
|
+Examples (b = BCLK, l = LRC)

|
+ASoC Codec Driver
|
|
+=================
|
|
+
|
|
+The codec driver is generic and hardware independent code that configures the
|
|
+codec to provide audio capture and playback. It should contain no code that is
|
|
+specific to the target platform or machine. All platform and machine specific
|
|
+code should be added to the platform and machine drivers respectively.
|
|
+
|
|
+Each codec driver must provide the following features:-
|
|
+
|
|
+ 1) Digital audio interface (DAI) description
|
|
+ 2) Digital audio interface configuration
|
|
+ 3) PCM's description
|
|
+ 4) Codec control IO - using I2C, 3 Wire(SPI) or both API's
|
|
+ 5) Mixers and audio controls
|
|
+ 6) Sysclk configuration
|
|
+ 7) Codec audio operations
|
|
+
|
|
+Optionally, codec drivers can also provide:-
|
|
+
|
|
+ 8) DAPM description.
|
|
+ 9) DAPM event handler.
|
|
+10) DAC Digital mute control.
|
|
+
|
|
+It's probably best to use this guide in conjuction with the existing codec
|
|
+driver code in sound/soc/codecs/
|
|
+
|
|
+ASoC Codec driver breakdown
|
|
+===========================
|
|
+
|
|
+1 - Digital Audio Interface (DAI) description
|
|
+---------------------------------------------
|
|
+The DAI is a digital audio data transfer link between the codec and host SoC
|
|
+CPU. It typically has data transfer capabilities in both directions
|
|
+(playback and capture) and can run at a variety of different speeds.
|
|
+Supported interfaces currently include AC97, I2S and generic PCM style links.
|
|
+Please read DAI.txt for implementation information.
|
|
+
|
|
+
|
|
+2 - Digital Audio Interface (DAI) configuration
|
|
+-----------------------------------------------
|
|
+DAI configuration is handled by the codec_pcm_prepare function and is
|
|
+responsible for configuring and starting the DAI on the codec. This can be
|
|
+called multiple times and is atomic. It can access the runtime parameters.
|
|
+
|
|
+This usually consists of a large function with numerous switch statements to
|
|
+set up each configuration option. These options are set by the core at runtime.
|
|
+
|
|
+
|
|
+3 - Codec PCM's
|
|
+---------------
|
|
+Each codec must have it's PCM's defined. This defines the number of channels,
|
|
+stream names, callbacks and codec name. It is also used to register the DAI
|
|
+with the ASoC core. The PCM structure also associates the DAI capabilities with
|
|
+the ALSA PCM.
|
|
+
|
|
+e.g.
|
|
+
|
|
+static struct snd_soc_pcm_codec wm8731_pcm_client = {
|
|
+ .name = "WM8731",
|
|
+ .playback = {
|
|
+ .stream_name = "Playback",
|
|
+ .channels_min = 1,
|
|
+ .channels_max = 2,
|
|
+ },
|
|
+ .capture = {
|
|
+ .stream_name = "Capture",
|
|
+ .channels_min = 1,
|
|
+ .channels_max = 2,
|
|
+ },
|
|
+ .config_sysclk = wm8731_config_sysclk,
|
|
+ .ops = {
|
|
+ .prepare = wm8731_pcm_prepare,
|
|
+ },
|
|
+ .caps = {
|
|
+ .num_modes = ARRAY_SIZE(wm8731_hwfmt),
|
|
+ .modes = &wm8731_hwfmt[0],
|
|
+ },
|
|
+};
|
|
+
|
|
+
|
|
+4 - Codec control IO
|
|
+--------------------
|
|
+The codec can ususally be controlled via an I2C or SPI style interface (AC97
|
|
+combines control with data in the DAI). The codec drivers will have to provide
|
|
+functions to read and write the codec registers along with supplying a register
|
|
+cache:-
|
|
+
|
|
+ /* IO control data and register cache */
|
|
+ void *control_data; /* codec control (i2c/3wire) data */
|
|
+ void *reg_cache;
|
|
+
|
|
+Codec read/write should do any data formatting and call the hardware read write
|
|
+below to perform the IO. These functions are called by the core and alsa when
|
|
+performing DAPM or changing the mixer:-
|
|
+
|
|
+ unsigned int (*read)(struct snd_soc_codec *, unsigned int);
|
|
+ int (*write)(struct snd_soc_codec *, unsigned int, unsigned int);
|
|
+
|
|
+Codec hardware IO functions - usually points to either the I2C, SPI or AC97
|
|
+read/write:-
|
|
+
|
|
+ hw_write_t hw_write;
|
|
+ hw_read_t hw_read;
|
|
+
|
|
+
|
|
+5 - Mixers and audio controls
|
|
+-----------------------------
|
|
+All the codec mixers and audio controls can be defined using the convenience
|
|
+macros defined in soc.h.
|
|
+
|
|
+ #define SOC_SINGLE(xname, reg, shift, mask, invert)
|
|
+
|
|
+Defines a single control as follows:-
|
|
+
|
|
+ xname = Control name e.g. "Playback Volume"
|
|
+ reg = codec register
|
|
+ shift = control bit(s) offset in register
|
|
+ mask = control bit size(s) e.g. mask of 7 = 3 bits
|
|
+ invert = the control is inverted
|
|
+
|
|
+Other macros include:-
|
|
+
|
|
+ #define SOC_DOUBLE(xname, reg, shift_left, shift_right, mask, invert)
|
|
+
|
|
+A stereo control
|
|
+
|
|
+ #define SOC_DOUBLE_R(xname, reg_left, reg_right, shift, mask, invert)
|
|
+
|
|
+A stereo control spanning 2 registers
|
|
+
|
|
+ #define SOC_ENUM_SINGLE(xreg, xshift, xmask, xtexts)
|
|
+
|
|
+Defines an single enumerated control as follows:-
|
|
+
|
|
+ xreg = register
|
|
+ xshift = control bit(s) offset in register
|
|
+ xmask = control bit(s) size
|
|
+ xtexts = pointer to array of strings that describe each setting
|
|
+
|
|
+ #define SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, xmask, xtexts)
|
|
+
|
|
+Defines a stereo enumerated control
|
|
+
|
|
+
|
|
+6 - System clock configuration.
|
|
+-------------------------------
|
|
+The system clock that drives the audio subsystem can change depending on sample
|
|
+rate and the system power state. i.e.
|
|
+
|
|
+o Higher sample rates sometimes need a higher system clock.
|
|
+o Low system power states can sometimes limit the available clocks.
|
|
+
|
|
+This function is a callback that the machine driver can call to set and
|
|
+determine if the clock and sample rate combination is supported by the codec at
|
|
+the present time (and system state).
|
|
+
|
|
+NOTE: If the codec has a PLL then it has a lot more flexability wrt clock and
|
|
+sample rate combinations.
|
|
+
|
|
+Your config_sysclock function should return the MCLK if it's a valid
|
|
+combination for your codec else 0;
|
|
+
|
|
+Please read clocking.txt now.
|
|
+
|
|
+
|
|
+7 - Codec Audio Operations
|
|
+--------------------------
|
|
+The codec driver also supports the following alsa operations:-
|
|
+
|
|
+/* SoC audio ops */
|
|
+struct snd_soc_ops {
|
|
+ int (*startup)(snd_pcm_substream_t *);
|
|
+ void (*shutdown)(snd_pcm_substream_t *);
|
|
+ int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
|
|
+ int (*hw_free)(snd_pcm_substream_t *);
|
|
+ int (*prepare)(snd_pcm_substream_t *);
|
|
+};
|
|
+
|
|
+Please refer to the alsa driver PCM documentation for details.
|
|
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
|
|
+
|
|
+
|
|
+8 - DAPM description.
|
|
+---------------------
|
|
+The Dynamic Audio Power Management description describes the codec's power
|
|
+components, their relationships and registers to the ASoC core. Please read
|
|
+dapm.txt for details of building the description.
|
|
+
|
|
+Please also see the examples in other codec drivers.
|
|
+
|
|
+
|
|
+9 - DAPM event handler
|
|
+----------------------
|
|
+This function is a callback that handles codec domain PM calls and system
|
|
+domain PM calls (e.g. suspend and resume). It's used to put the codec to sleep
|
|
+when not in use.
|
|
+
|
|
+Power states:-
|
|
+
|
|
+ SNDRV_CTL_POWER_D0: /* full On */
|
|
+ /* vref/mid, clk and osc on, active */
|
|
+
|
|
+ SNDRV_CTL_POWER_D1: /* partial On */
|
|
+ SNDRV_CTL_POWER_D2: /* partial On */
|
|
+
|
|
+ SNDRV_CTL_POWER_D3hot: /* Off, with power */
|
|
+ /* everything off except vref/vmid, inactive */
|
|
+
|
|
+ SNDRV_CTL_POWER_D3cold: /* Everything Off, without power */
|
|
+
|
|
+
|
|
+10 - Codec DAC digital mute control.
|
|
+------------------------------------
|
|
+Most codecs have a digital mute before the DAC's that can be used to minimise
|
|
+any system noise. The mute stops any digital data from entering the DAC.
|
|
+
|
|
+A callback can be created that is called by the core for each codec DAI when the
|
|
+mute is applied or freed.
|
|
+
|
|
+i.e.
|
|
+
|
|
+static int wm8974_mute(struct snd_soc_codec *codec,
|
|
+ struct snd_soc_codec_dai *dai, int mute)
|
|
+{
|
|
+ u16 mute_reg = wm8974_read_reg_cache(codec, WM8974_DAC) & 0xffbf;
|
|
+ if(mute)
|
|
+ wm8974_write(codec, WM8974_DAC, mute_reg | 0x40);
|
|
+ else
|
|
+ wm8974_write(codec, WM8974_DAC, mute_reg);
|
|
+ return 0;
|
|
+}

|
+Dynamic Audio Power Management for Portable Devices
|
|
+===================================================
|
|
+
|
|
+1. Description
|
|
+==============
|
|
+
|
|
+Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices
|
|
+to use the minimum amount of power within the audio subsystem at all times. It
|
|
+is independent of other kernel PM and as such, can easily co-exist with the
|
|
+other PM systems.
|
|
+
|
|
+DAPM is also completely transparent to all user space applications as all power
|
|
+switching is done within the ASoC core. No code changes or recompiling are
|
|
+required for user space applications. DAPM makes power switching descisions based
|
|
+upon any audio stream (capture/playback) activity and audio mixer settings
|
|
+within the device.
|
|
+
|
|
+DAPM spans the whole machine. It covers power control within the entire audio
|
|
+subsystem, this includes internal codec power blocks and machine level power
|
|
+systems.
|
|
+
|
|
+There are 4 power domains within DAPM
|
|
+
|
|
+ 1. Codec domain - VREF, VMID (core codec and audio power)
|
|
+ Usually controlled at codec probe/remove and suspend/resume, although
|
|
+ can be set at stream time if power is not needed for sidetone, etc.
|
|
+
|
|
+ 2. Platform/Machine domain - physically connected inputs and outputs
|
|
+ Is platform/machine and user action specific, is configured by the
|
|
+ machine driver and responds to asynchronous events e.g when HP
|
|
+ are inserted
|
|
+
|
|
+ 3. Path domain - audio susbsystem signal paths
|
|
+ Automatically set when mixer and mux settings are changed by the user.
|
|
+ e.g. alsamixer, amixer.
|
|
+
|
|
+ 4. Stream domain - DAC's and ADC's.
|
|
+ Enabled and disabled when stream playback/capture is started and
|
|
+ stopped respectively. e.g. aplay, arecord.
|
|
+
|
|
+All DAPM power switching descisons are made automatically by consulting an audio
|
|
+routing map of the whole machine. This map is specific to each machine and
|
|
+consists of the interconnections between every audio component (including
|
|
+internal codec components). All audio components that effect power are called
|
|
+widgets hereafter.
|
|
+
|
|
+
|
|
+2. DAPM Widgets
|
|
+===============
|
|
+
|
|
+Audio DAPM widgets fall into a number of types:-
|
|
+
|
|
+ o Mixer - Mixes several analog signals into a single analog signal.
|
|
+ o Mux - An analog switch that outputs only 1 of it's inputs.
|
|
+ o PGA - A programmable gain amplifier or attenuation widget.
|
|
+ o ADC - Analog to Digital Converter
|
|
+ o DAC - Digital to Analog Converter
|
|
+ o Switch - An analog switch
|
|
+ o Input - A codec input pin
|
|
+ o Output - A codec output pin
|
|
+ o Headphone - Headphone (and optional Jack)
|
|
+ o Mic - Mic (and optional Jack)
|
|
+ o Line - Line Input/Output (and optional Jack)
|
|
+ o Speaker - Speaker
|
|
+ o Pre - Special PRE widget (exec before all others)
|
|
+ o Post - Special POST widget (exec after all others)
|
|
+
|
|
+(Widgets are defined in include/sound/soc-dapm.h)
|
|
+
|
|
+Widgets are usually added in the codec driver and the machine driver. There are
|
|
+convience macros defined in soc-dapm.h that can be used to quickly build a
|
|
+list of widgets of the codecs and machines DAPM widgets.
|
|
+
|
|
+Most widgets have a name, register, shift and invert. Some widgets have extra
|
|
+parameters for stream name and kcontrols.
|
|
+
|
|
+
|
|
+2.1 Stream Domain Widgets
|
|
+-------------------------
|
|
+
|
|
+Stream Widgets relate to the stream power domain and only consist of ADC's
|
|
+(analog to digital converters) and DAC's (digital to analog converters).
|
|
+
|
|
+Stream widgets have the following format:-
|
|
+
|
|
+SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert),
|
|
+
|
|
+NOTE: the stream name must match the corresponding stream name in your codecs
|
|
+snd_soc_codec_dai.
|
|
+
|
|
+e.g. stream widgets for HiFi playback and capture
|
|
+
|
|
+SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1),
|
|
+SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1),
|
|
+
|
|
+
|
|
+2.2 Path Domain Widgets
|
|
+-----------------------
|
|
+
|
|
+Path domain widgets have a ability to control or effect the audio signal or
|
|
+audio paths within the audio subsystem. They have the following form:-
|
|
+
|
|
+SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls)
|
|
+
|
|
+Any widget kcontrols can be set using the controls and num_controls members.
|
|
+
|
|
+e.g. Mixer widget (the kcontrols are declared first)
|
|
+
|
|
+/* Output Mixer */
|
|
+static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = {
|
|
+SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0),
|
|
+SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0),
|
|
+SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0),
|
|
+};
|
|
+
|
|
+SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls,
|
|
+ ARRAY_SIZE(wm8731_output_mixer_controls)),
|
|
+
|
|
+
|
|
+2.3 Platform/Machine domain Widgets
|
|
+-----------------------------------
|
|
+
|
|
+Machine widgets are different from codec widgets in that they don't have a
|
|
+codec register bit associated with them. A machine widget is assigned to each
|
|
+machine audio component (non codec) that can be independently powered. e.g.
|
|
+
|
|
+ o Speaker Amp
|
|
+ o Microphone Bias
|
|
+ o Jack connectors
|
|
+
|
|
+A machine widget can have an optional call back.
|
|
+
|
|
+e.g. Jack connector widget for an external Mic that enables Mic Bias
|
|
+when the Mic is inserted:-
|
|
+
|
|
+static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event)
|
|
+{
|
|
+ if(SND_SOC_DAPM_EVENT_ON(event))
|
|
+ set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
|
|
+ else
|
|
+ reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
|
|
+
|
|
+ return 0;
|
|
+}
|
|
+
|
|
+SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias),
|
|
+
|
|
+
|
|
+2.4 Codec Domain
|
|
+----------------
|
|
+
|
|
+The Codec power domain has no widgets and is handled by the codecs DAPM event
|
|
+handler. This handler is called when the codec powerstate is changed wrt to any
|
|
+stream event or by kernel PM events.
|
|
+
|
|
+
|
|
+2.5 Virtual Widgets
|
|
+-------------------
|
|
+
|
|
+Sometimes widgets exist in the codec or machine audio map that don't have any
|
|
+corresponding register bit for power control. In this case it's necessary to
|
|
+create a virtual widget - a widget with no control bits e.g.
|
|
+
|
|
+SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0),
|
|
+
|
|
+This can be used to merge to signal paths together in software.
|
|
+
|
|
+After all the widgets have been defined, they can then be added to the DAPM
|
|
+subsystem individually with a call to snd_soc_dapm_new_control().
|
|
+
|
|
+
|
|
+3. Codec Widget Interconnections
|
|
+================================
|
|
+
|
|
+Widgets are connected to each other within the codec and machine by audio
|
|
+paths (called interconnections). Each interconnection must be defined in order
|
|
+to create a map of all audio paths between widgets.
|
|
+This is easiest with a diagram of the codec (and schematic of the machine audio
|
|
+system), as it requires joining widgets together via their audio signal paths.
|
|
+
|
|
+i.e. from the WM8731 codec's output mixer (wm8731.c)
|
|
+
|
|
+The WM8731 output mixer has 3 inputs (sources)
|
|
+
|
|
+ 1. Line Bypass Input
|
|
+ 2. DAC (HiFi playback)
|
|
+ 3. Mic Sidetone Input
|
|
+
|
|
+Each input in this example has a kcontrol associated with it (defined in example
|
|
+above) and is connected to the output mixer via it's kcontrol name. We can now
|
|
+connect the destination widget (wrt audio signal) with it's source widgets.
|
|
+
|
|
+ /* output mixer */
|
|
+ {"Output Mixer", "Line Bypass Switch", "Line Input"},
|
|
+ {"Output Mixer", "HiFi Playback Switch", "DAC"},
|
|
+ {"Output Mixer", "Mic Sidetone Switch", "Mic Bias"},
|
|
+
|
|
+So we have :-
|
|
+
|
|
+ Destination Widget <=== Path Name <=== Source Widget
|
|
+
|
|
+Or:-
|
|
+
|
|
+ Sink, Path, Source
|
|
+
|
|
+Or :-
|
|
+
|
|
+ "Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch".
|
|
+
|
|
+When there is no path name connecting widgets (e.g. a direct connection) we
|
|
+pass NULL for the path name.
|
|
+
|
|
+Interconnections are created with a call to:-
|
|
+
|
|
+snd_soc_dapm_connect_input(codec, sink, path, source);
|
|
+
|
|
+Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and
|
|
+interconnections have been registered with the core. This causes the core to
|
|
+scan the codec and machine so that the internal DAPM state matches the
|
|
+physical state of the machine.
|
|
+
|
|
+
|
|
+3.1 Machine Widget Interconnections
|
|
+-----------------------------------
|
|
+Machine widget interconnections are created in the same way as codec ones and
|
|
+directly connect the codec pins to machine level widgets.
|
|
+
|
|
+e.g. connects the speaker out codec pins to the internal speaker.
|
|
+
|
|
+ /* ext speaker connected to codec pins LOUT2, ROUT2 */
|
|
+ {"Ext Spk", NULL , "ROUT2"},
|
|
+ {"Ext Spk", NULL , "LOUT2"},
|
|
+
|
|
+This allows the DAPM to power on and off pins that are connected (and in use)
|
|
+and pins that are NC respectively.
|
|
+
|
|
+
|
|
+4 Endpoint Widgets
|
|
+===================
|
|
+An endpoint is a start or end point (widget) of an audio signal within the
|
|
+machine and includes the codec. e.g.
|
|
+
|
|
+ o Headphone Jack
|
|
+ o Internal Speaker
|
|
+ o Internal Mic
|
|
+ o Mic Jack
|
|
+ o Codec Pins
|
|
+
|
|
+When a codec pin is NC it can be marked as not used with a call to
|
|
+
|
|
+snd_soc_dapm_set_endpoint(codec, "Widget Name", 0);
|
|
+
|
|
+The last argument is 0 for inactive and 1 for active. This way the pin and its
|
|
+input widget will never be powered up and consume power.
|
|
+
|
|
+This also applies to machine widgets. e.g. if a headphone is connected to a
|
|
+jack then the jack can be marked active. If the headphone is removed, then
|
|
+the headphone jack can be marked inactive.
|
|
+
|
|
+
|
|
+5 DAPM Widget Events
|
|
+====================
|
|
+
|
|
+Some widgets can register their interest with the DAPM core in PM events.
|
|
+e.g. A Speaker with an amplifier registers a widget so the amplifier can be
|
|
+powered only when the spk is in use.
|
|
+
|
|
+/* turn speaker amplifier on/off depending on use */
|
|
+static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event)
|
|
+{
|
|
+ if (SND_SOC_DAPM_EVENT_ON(event))
|
|
+ set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
|
|
+ else
|
|
+ reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
|
|
+
|
|
+ return 0;
|
|
+}
|
|
+
|
|
+/* corgi machine dapm widgets */
|
|
+static const struct snd_soc_dapm_widget wm8731_dapm_widgets =
|
|
+ SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event);
|
|
+
|
|
+Please see soc-dapm.h for all other widgets that support events.
|
|
+
|
|
+
|
|
+5.1 Event types
|
|
+---------------
|
|
+
|
|
+The following event types are supported by event widgets.
|
|
+
|
|
+/* dapm event types */
|
|
+#define SND_SOC_DAPM_PRE_PMU 0x1 /* before widget power up */
|
|
+#define SND_SOC_DAPM_POST_PMU 0x2 /* after widget power up */
|
|
+#define SND_SOC_DAPM_PRE_PMD 0x4 /* before widget power down */
|
|
+#define SND_SOC_DAPM_POST_PMD 0x8 /* after widget power down */
|
|
+#define SND_SOC_DAPM_PRE_REG 0x10 /* before audio path setup */
|
|
+#define SND_SOC_DAPM_POST_REG 0x20 /* after audio path setup */

|
+ASoC Machine Driver
|
|
+===================
|
|
+
|
|
+The ASoC machine (or board) driver is the code that glues together the platform
|
|
+and codec drivers.
|
|
+
|
|
+The machine driver can contain codec and platform specific code. It registers
|
|
+the audio subsystem with the kernel as a platform device and is represented by
|
|
+the following struct:-
|
|
+
|
|
+/* SoC machine */
|
|
+struct snd_soc_machine {
|
|
+ char *name;
|
|
+
|
|
+ int (*probe)(struct platform_device *pdev);
|
|
+ int (*remove)(struct platform_device *pdev);
|
|
+
|
|
+ /* the pre and post PM functions are used to do any PM work before and
|
|
+ * after the codec and DAI's do any PM work. */
|
|
+ int (*suspend_pre)(struct platform_device *pdev, pm_message_t state);
|
|
+ int (*suspend_post)(struct platform_device *pdev, pm_message_t state);
|
|
+ int (*resume_pre)(struct platform_device *pdev);
|
|
+ int (*resume_post)(struct platform_device *pdev);
|
|
+
|
|
+ /* machine stream operations */
|
|
+ struct snd_soc_ops *ops;
|
|
+
|
|
+ /* CPU <--> Codec DAI links */
|
|
+ struct snd_soc_dai_link *dai_link;
|
|
+ int num_links;
|
|
+};
|
|
+
|
|
+probe()/remove()
|
|
+----------------
|
|
+probe/remove are optional. Do any machine specific probe here.
|
|
+
|
|
+
|
|
+suspend()/resume()
|
|
+------------------
|
|
+The machine driver has pre and post versions of suspend and resume to take care
|
|
+of any machine audio tasks that have to be done before or after the codec, DAI's
|
|
+and DMA is suspended and resumed. Optional.
|
|
+
|
|
+
|
|
+Machine operations
|
|
+------------------
|
|
+The machine specific audio operations can be set here. Again this is optional.
|
|
+
|
|
+
|
|
+Machine DAI Configuration
|
|
+-------------------------
|
|
+The machine DAI configuration glues all the codec and CPU DAI's together. It can
|
|
+also be used to set up the DAI system clock and for any machine related DAI
|
|
+initialisation e.g. the machine audio map can be connected to the codec audio
|
|
+map, unconnnected codec pins can be set as such. Please see corgi.c, spitz.c
|
|
+for examples.
|
|
+
|
|
+struct snd_soc_dai_link is used to set up each DAI in your machine. e.g.
|
|
+
|
|
+/* corgi digital audio interface glue - connects codec <--> CPU */
|
|
+static struct snd_soc_dai_link corgi_dai = {
|
|
+ .name = "WM8731",
|
|
+ .stream_name = "WM8731",
|
|
+ .cpu_dai = &pxa_i2s_dai,
|
|
+ .codec_dai = &wm8731_dai,
|
|
+ .init = corgi_wm8731_init,
|
|
+ .config_sysclk = corgi_config_sysclk,
|
|
+};
|
|
+
|
|
+struct snd_soc_machine then sets up the machine with it's DAI's. e.g.
|
|
+
|
|
+/* corgi audio machine driver */
|
|
+static struct snd_soc_machine snd_soc_machine_corgi = {
|
|
+ .name = "Corgi",
|
|
+ .dai_link = &corgi_dai,
|
|
+ .num_links = 1,
|
|
+ .ops = &corgi_ops,
|
|
+};
|
|
+
|
|
+
|
|
+Machine Audio Subsystem
|
|
+-----------------------
|
|
+
|
|
+The machine soc device glues the platform, machine and codec driver together.
|
|
+Private data can also be set here. e.g.
|
|
+
|
|
+/* corgi audio private data */
|
|
+static struct wm8731_setup_data corgi_wm8731_setup = {
|
|
+ .i2c_address = 0x1b,
|
|
+};
|
|
+
|
|
+/* corgi audio subsystem */
|
|
+static struct snd_soc_device corgi_snd_devdata = {
|
|
+ .machine = &snd_soc_machine_corgi,
|
|
+ .platform = &pxa2xx_soc_platform,
|
|
+ .codec_dev = &soc_codec_dev_wm8731,
|
|
+ .codec_data = &corgi_wm8731_setup,
|
|
+};
|
|
+
|
|
+
|
|
+Machine Power Map
|
|
+-----------------
|
|
+
|
|
+The machine driver can optionally extend the codec power map and to become an
|
|
+audio power map of the audio subsystem. This allows for automatic power up/down
|
|
+of speaker/HP amplifiers, etc. Codec pins can be connected to the machines jack
|
|
+sockets in the machine init function. See soc/pxa/spitz.c and dapm.txt for
|
|
+details.
|
|
+
|
|
+
|
|
+Machine Controls
|
|
+----------------
|
|
+
|
|
+Machine specific audio mixer controls can be added in the dai init function.

+ALSA SoC Layer
|
|
+==============
|
|
+
|
|
+The overall project goal of the ALSA System on Chip (ASoC) layer is to provide
|
|
+better ALSA support for embedded system on chip procesors (e.g. pxa2xx, au1x00,
|
|
+iMX, etc) and portable audio codecs. Currently there is some support in the
|
|
+kernel for SoC audio, however it has some limitations:-
|
|
+
|
|
+ * Currently, codec drivers are often tightly coupled to the underlying SoC
|
|
+ cpu. This is not ideal and leads to code duplication i.e. Linux now has 4
|
|
+ different wm8731 drivers for 4 different SoC platforms.
|
|
+
|
|
+ * There is no standard method to signal user initiated audio events.
|
|
+ e.g. Headphone/Mic insertion, Headphone/Mic detection after an insertion
|
|
+ event. These are quite common events on portable devices and ofter require
|
|
+ machine specific code to re route audio, enable amps etc after such an event.
|
|
+
|
|
+ * Current drivers tend to power up the entire codec when playing
|
|
+ (or recording) audio. This is fine for a PC, but tends to waste a lot of
|
|
+ power on portable devices. There is also no support for saving power via
|
|
+ changing codec oversampling rates, bias currents, etc.
|
|
+
|
|
+
|
|
+ASoC Design
|
|
+===========
|
|
+
|
|
+The ASoC layer is designed to address these issues and provide the following
|
|
+features :-
|
|
+
|
|
+ * Codec independence. Allows reuse of codec drivers on other platforms
|
|
+ and machines.
|
|
+
|
|
+ * Easy I2S/PCM audio interface setup between codec and SoC. Each SoC interface
|
|
+ and codec registers it's audio interface capabilities with the core and are
|
|
+ subsequently matched and configured when the application hw params are known.
|
|
+
|
|
+ * Dynamic Audio Power Management (DAPM). DAPM automatically sets the codec to
|
|
+ it's minimum power state at all times. This includes powering up/down
|
|
+ internal power blocks depending on the internal codec audio routing and any
|
|
+ active streams.
|
|
+
|
|
+ * Pop and click reduction. Pops and clicks can be reduced by powering the
|
|
+ codec up/down in the correct sequence (including using digital mute). ASoC
|
|
+ signals the codec when to change power states.
|
|
+
|
|
+ * Machine specific controls: Allow machines to add controls to the sound card
|
|
+ e.g. volume control for speaker amp.
|
|
+
|
|
+To achieve all this, ASoC basically splits an embedded audio system into 3
|
|
+components :-
|
|
+
|
|
+ * Codec driver: The codec driver is platform independent and contains audio
|
|
+ controls, audio interface capabilities, codec dapm definition and codec IO
|
|
+ functions.
|
|
+
|
|
+ * Platform driver: The platform driver contains the audio dma engine and audio
|
|
+ interface drivers (e.g. I2S, AC97, PCM) for that platform.
|
|
+
|
|
+ * Machine driver: The machine driver handles any machine specific controls and
|
|
+ audio events. i.e. turing on an amp at start of playback.

+ASoC Platform Driver
|
|
+====================
|
|
+
|
|
+An ASoC platform driver can be divided into audio DMA and SoC DAI configuration
|
|
+and control. The platform drivers only target the SoC CPU and must have no board
|
|
+specific code.
|
|
+
|
|
+Audio DMA
|
|
+=========
|
|
+
|
|
+The platform DMA driver optionally supports the following alsa operations:-
|
|
+
|
|
+/* SoC audio ops */
|
|
+struct snd_soc_ops {
|
|
+ int (*startup)(snd_pcm_substream_t *);
|
|
+ void (*shutdown)(snd_pcm_substream_t *);
|
|
+ int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
|
|
+ int (*hw_free)(snd_pcm_substream_t *);
|
|
+ int (*prepare)(snd_pcm_substream_t *);
|
|
+ int (*trigger)(snd_pcm_substream_t *, int);
|
|
+};
|
|
+
|
|
+The platform driver exports it's DMA functionailty via struct snd_soc_platform:-
|
|
+
|
|
+struct snd_soc_platform {
|
|
+ char *name;
|
|
+
|
|
+ int (*probe)(struct platform_device *pdev);
|
|
+ int (*remove)(struct platform_device *pdev);
|
|
+ int (*suspend)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
|
|
+ int (*resume)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
|
|
+
|
|
+ /* pcm creation and destruction */
|
|
+ int (*pcm_new)(snd_card_t *, struct snd_soc_codec_dai *, snd_pcm_t *);
|
|
+ void (*pcm_free)(snd_pcm_t *);
|
|
+
|
|
+ /* platform stream ops */
|
|
+ snd_pcm_ops_t *pcm_ops;
|
|
+};
|
|
+
|
|
+Please refer to the alsa driver documentation for details of audio DMA.
|
|
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
|
|
+
|
|
+An example DMA driver is soc/pxa/pxa2xx-pcm.c
|
|
+
|
|
+
|
|
+SoC DAI Drivers
|
|
+===============
|
|
+
|
|
+Each SoC DAI driver must provide the following features:-
|
|
+
|
|
+ 1) Digital audio interface (DAI) description
|
|
+ 2) Digital audio interface configuration
|
|
+ 3) PCM's description
|
|
+ 4) Sysclk configuration
|
|
+ 5) Suspend and resume (optional)
|
|
+
|
|
+Please see codec.txt for a description of items 1 - 4.

|
+Audio Pops and Clicks
|
|
+=====================
|
|
+
|
|
+Pops and clicks are unwanted audio artifacts caused by the powering up and down
|
|
+of components within the audio subsystem. This is noticable on PC's when an audio
|
|
+module is either loaded or unloaded (at module load time the sound card is
|
|
+powered up and causes a popping noise on the speakers).
|
|
+
|
|
+Pops and clicks can be more frequent on portable systems with DAPM. This is because
|
|
+the components within the subsystem are being dynamically powered depending on
|
|
+the audio usage and this can subsequently cause a small pop or click every time a
|
|
+component power state is changed.
|
|
+
|
|
+
|
|
+Minimising Playback Pops and Clicks
|
|
+===================================
|
|
+
|
|
+Playback pops in portable audio subsystems cannot be completely eliminated atm,
|
|
+however future audio codec hardware will have better pop and click supression.
|
|
+Pops can be reduced within playback by powering the audio components in a
|
|
+specific order. This order is different for startup and shutdown and follows
|
|
+some basic rules:-
|
|
+
|
|
+ Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
|
|
+
|
|
+ Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
|
|
+
|
|
+This assumes that the codec PCM output path from the DAC is via a mixer and then
|
|
+a PGA (programmable gain amplifier) before being output to the speakers.
|
|
+
|
|
+
|
|
+Minimising Capture Pops and Clicks
|
|
+==================================
|
|
+
|
|
+Capture artifacts are somewhat easier to get rid as we can delay activating the
|
|
+ADC until all the pops have occured. This follows similar power rules to
|
|
+playback in that components are powered in a sequence depending upon stream
|
|
+startup or shutdown.
|
|
+
|
|
+ Startup Order - Input PGA --> Mixers --> ADC
|
|
+
|
|
+ Shutdown Order - ADC --> Mixers --> Input PGA
|
|
+
|
|
+
|
|
+Zipper Noise
|
|
+============
|
|
+An unwanted zipper noise can occur within the audio playback or capture stream
|
|
+when a volume control is changed near its maximum gain value. The zipper noise
|
|
+is heard when the gain increase or decrease changes the mean audio signal
|
|
+amplitude too quickly. It can be minimised by enabling the zero cross setting
|
|
+for each volume control. The ZC forces the gain change to occur when the signal
|
|
+crosses the zero amplitude line.

|
|
+ * The WM8753 is a low power, high quality stereo codec with integrated PCM

|
+ * codec designed for portable digital telephony applications.
|
|
+ *
|
|
+ * Dual DAI:-
|
|
+ *
|
|
+ * This driver support 2 DAI PCM's. This makes the default PCM available for
|
|
+ * HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
|
|
+ * voice.
|
|
+ *
|
|
+ * Please note that the voice PCM can be connected directly to a Bluetooth
|
|
+ * codec or GSM modem and thus cannot be read or written to, although it is
|
|
+ * available to be configured with snd_hw_params(), etc and kcontrols in the
|
|
+ * normal alsa manner.
|
|
+ *
|
|
+ * Fast DAI switching:-
|
|
+ *
|
|
+ * The driver can now fast switch between the DAI configurations via a
|
|
+ * an alsa kcontrol. This allows the PCM to remain open.

|
|
+ * 15th May 2006 Initial version.
|
|
+ *
|
|
+ * This is example code to demonstrate connecting a bluetooth codec to the PCM
|
|
+ * DAI on the WM8753 codec on the Intel Mainstone platform. It is by no means
|
|
+ * complete as it requires code to control the BT codec.
|
|
+ *
|
|
+ * The architecture consists of the WM8753 HIFI DAI connected to the PXA27x
|
|
+ * I2S controller and the WM8753 PCM DAI connected to the bluetooth DAI. The
|
|
+ * bluetooth codec and wm8753 are controlled via I2C. Audio is routed between
|
|
+ * the PXA27x and the bluetooth via internal WM8753 analog paths.
|
|
+ *
|
|
+ * This example supports the following audio input/outputs.
|
|
+ *
|
|
+ * o Board mounted Mic and Speaker (spk has amplifier)
|
|
+ * o Headphones via jack socket
|
|
+ * o BT source and sink
|
|
+ *
|
|
+ * This driver is not the bluetooth codec driver. This driver only calls
|
|
+ * functions from the Bluetooth driver to set up it's PCM DAI.
|
|
+ *
|
|
+ * It's intended to use the driver as follows:-
|
|
+ *
|
|
+ * 1. open() WM8753 PCM audio device.
|
|
+ * 2. configure PCM audio device (rate etc) - sets up WM8753 PCM DAI,
|
|
+ * this should also set up the BT codec DAI (via calling bt driver).
|
|
+ * 3. configure codec audio mixer paths.
|
|
+ * 4. open(), configure and read/write HIFI audio device - to Tx/Rx voice
|
|
+ *
|
|
+ * The PCM audio device is opened but IO is never performed on it as the IO is
|
|
+ * directly between the codec and the BT codec (and not the CPU).

|
|
+ * Revision history
|
|
+ * 12th Aug 2005 Initial version.
|
|
+ * 25th Oct 2005 Implemented path power domain.
|
|
+ * 18th Dec 2005 Implemented machine and stream level power domain.
|
|
+ *
|
|
+ * Features:
|
|
+ * o Changes power status of internal codec blocks depending on the
|
|
+ * dynamic configuration of codec internal audio paths and active
|
|
+ * DAC's/ADC's.
|
|
+ * o Platform power domain - can support external components i.e. amps and
|
|
+ * mic/meadphone insertion events.
|
|
+ * o Automatic Mic Bias support
|
|
+ * o Jack insertion power event initiation - e.g. hp insertion will enable
|
|
+ * sinks, dacs, etc
|
|
+ * o Delayed powerdown of audio susbsytem to reduce pops between a quick
|
|
+ * device reopen.
|
|
+ *
|
|
+ * Todo:
|
|
+ * o DAPM power change sequencing - allow for configurable per
|
|
+ * codec sequences.
|
|
+ * o Support for analogue bias optimisation.
|
|
+ * o Support for reduced codec oversampling rates.
|
|
+ * o Support for reduced codec bias currents.
