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_A (1 << 3) /* L data msb after FRM */ ++#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_NF (1 << 10) /* invert bclk + nor 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.

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.

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 */ +Index: linux-2.6-pxa-new/Documentation/sound/alsa/soc/machine.txt +=================================================================== +--- /dev/null ++++ linux-2.6-pxa-new/Documentation/sound/alsa/soc/machine.txt +@@ -0,0 +1,114 @@ ++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.

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.

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.
