2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-07-04ASoC: tlv320aic3x: Add correct hw registers to Line1 cross connect muxesJarkko Nikula
Commit af46800 ("ASoC: Implement mux control sharing") revealed that "Left Line1[L | R] Mux" and "Right Line1[L | R] Mux" widgets were pointing to the same kcontrols and codec registers and thus soc-core falsely detected them as shared controls. This is actually wrong since there are separate registers in hardware that configure Line1L to RADC and Line1R to LADC cross connects so these muxes should not be shared.

2011-05-23ASoC: tlv320aic3x: Do soft reset to codec when going to bias off stateJarkko Nikula
TLV320AIC33, TLV320AIC34 and I believe others too in this family have some hw bugs that cause that analogue and digital VDD supplies remain leaking up to a few mA of current after certain use cases even the hw blocks inside codec are driven to off. Highest leakages occur after using the bypass paths inside codec but it is possible to get smaller leakages just by toggling mute switches in unused audio paths (i.e. no DAPM changes) while codec is on due another active audio path. While some cases are able to workaroud by making sure that e.g. output mixer switches are muted before powering down the output stage this doesn't help all the cases. Therefore use the software reset command to clear possible leakage currents since that works in every cases and affects only this codec instance. Only drawback is that now cache sync is required everytime when codec bias comes out from bias off state, not only when supply regulators were off.

2010-11-06ASoC: Decouple DAPM from CODECsLiam Girdwood
Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes.

2010-11-03ASoC: tlv320aic3x: Add support to shared common reset lineJarkko Nikula
This is aimed to configurations where multiple aic3x codecs share the same reset line and are powered from same supply voltages. Currently aic3x_probe will fail if trying to request already requested gpio_reset and passing -1 to another aic3x instances cause that those instances cannot release reset in aic3x_set_power. That is, another instances can work only if primary aic3x instance is powered and reset is released. Solve this by implementing a list of probed instances that is used for checking if other instance shares the same gpio_reset number. If a shared reset line exists, then only first instance tries to request and configure it and the last instance releases it. Runtime modifications are not needed since aic3x_regulator_event with help of regulator framework takes already care that reset is pulled down only when some or all supplies are disabled meaning that all instances using them are idle.

There is no need to reset the codec and perform cache sync if none of the supply regulators were not disabled.

HW writes are also needless when codec bias is off so cache_only flag is set independently of actual supply regulators state.

2010-09-20ASoC: tlv320aic3x: Add runtime regulator control to aic3x_set_bias_levelJarkko Nikula
Now all the regulators are disabled when entering into SND_SOC_BIAS_OFF and enabled when coming back to SND_SOC_BIAS_STANDBY state. Currently this runtime control happens only with suspend/resume as this patch does not change the default idle behavior. This patch manages all the regulators and reset since it seems that register sync is needed even if only analog supplies AVDD and DRVDD are disabled. This was noted when the system was running with idle behavior changed and IOVDD and DVDD were on. It is not known are all the registers needed to sync or only some subset of them. Therefore patch plays safe and does always full shutdown/power-up.

Purpose of this virtual Detection pin is to keep codec bias on whenever the GPIO or jack detection features are needed. Jack detection needs a mic bias so machine drivers can construct a following route for instance for keeping the path and codec bias on: "Input Jack" -> "Mic Bias xV" -> "Detection" -> detection block inside codec. For the GPIO the machine driver can force the pin on with snd_soc_dapm_force_enable_pin.

2010-08-28ASoC: tlv320aic3x: Sanitize output controlsJarkko Nikula
Currently output controls are not uniform. Some routes are adjusted by mono controls that don't match to associated mixer switch, many routes are not covered at all and stereo controls have following variants: - L-to-L & R-to-R - R-to-L & R-to-R - L-to-L & R-to-L This patch attempts to fix these issues. First, for the convenience, only direct L-to-L, R-to-R and [L | R]-to-Mono routes are controlled by the stereo controls. This logic is also used with the output pin mute controls so all of them except mono output are controlled by stereo switches. Then rest of the swapped L-to-R and R-to-L routes are controlled by the mono controls that map to mixer switches with a same name. Mixers can then associate these switches and volumes together.

2010-08-28ASoC: tlv320aic3x: Reimplement output mixersJarkko Nikula
It turned out that the output mixers and their routes were misdefined: They are not mixing output pins to internal signals but opposite. This has worked for direct left-to-left and right-to-right routes since for those there are complete routes. For swapped left-to-right and right-to-left routes this is not working since there are no routes defined between them. Another consequence is that those misdefined mixers are incorrectly routed to several output pins leading unnecessary pin powerings even if there is no route active to them. Fix these by reimplementing the output mixers and routes as they are in hardware. For completeness add also a few missing links between internal signals and outputs.

2010-08-12ASoC: multi-component - ASoC Multi-Component SupportLiam Girdwood
This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().
