2014-09-04ASoC: ssm2602: Cleanup manual bias level transitionsLars-Peter Clausen
Set the CODEC driver's suspend_bias_off flag rather than manually going to SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes the code a bit shorter and cleaner. While we are at it also remove the regcache_cache_only() calls from suspend/resume as there shouldn't be any IO between suspend and resume. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.

2014-09-04ASoC: Always run default suspend/resume codeLars-Peter Clausen
We do a bit more than just running the callbacks during suspend and resume these days (e.g. call regcache_mark_dirty() during suspend). But this is only when suspend and resume callbacks are specified for the driver, otherwise nothing is done. This means that drivers which don't want to do anything special during suspend and resume, but still want the standard operations to run, need to provide empty suspend and resume callback functions (rather than no callbacks). This patch updates the suspend and resume code to always run standard sequence regardless of whether suspend and resume handlers are provided.

2014-09-04ASoC: Add support for automatically going to BIAS_OFF on suspendLars-Peter Clausen
There is a substantial amount of drivers that in go to SND_SOC_BIAS_OFF on suspend and go back to SND_SOC_BIAS_SUSPEND on resume (Often this is even the only thing done in the suspend and resume handlers). This patch introduces a new suspend_bias_off flag, which when set by a driver will let the ASoC core automatically put the device's DAPM context at the SND_SOC_BIAS_OFF level during suspend. Once the device is resumed the DAPM context will go back to SND_SOC_BIAS_STANDBY (if the context is idle, otherwise to SND_SOC_BIAS_ON). This will allow us to remove a fair bit of duplicated code from the drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-09-04ASoC: Shutdown DAPM contexts when removing a cardLars-Peter Clausen
Currently when a ASoC sound card is unregistered we leave the individual components in their current state, just call the remove() callback and leave it to the drivers to do the proper shutdown/cleanup. This patch introduces a call to snd_soc_dapm_shutdown() when removing the card. This will make sure that all DAPM widgets are properly powered down and all DAPM contexts are put at the SND_SOC_BIAS_OFF level. This will ensure that all components are properly powered down when the card is removed. Since a lot of drivers manually go to SND_SOC_BIAS_OFF in their remove callback this will also allow us to remove a bit of duplicated code.

2014-09-03ALSA: hda - Add TLV_DB_SCALE_MUTE bit for relevant controlsTakashi Iwai
The DACs on Sigmatel/IDT codecs do mute at the lowest volume level, and in the earlier drivers, we passed TLV_DB_SCALE_MUTE bit for each volume control element like Speaker and Headphone as well as Master. Along with the translation to the generic parser, however, the TLV bit was lost for the slave controls (e.g. Speaker) but set only to Master. In theory this should have sufficed, but apps, particularly PA, do care the slave volume bits, so we seem to see a regression in the volume controls. This patch adds a flag to hda_gen_spec to specify the DAC mute feature, and adds the TLV bit properly for all relevant volume controls. Also, the TLV bit for vmaster is set in hda_generic.c, so that we can get rid of all tricks from the codec driver side. As the similar hack is applied to Conexant 5051 stuff, we can get rid of it as well. BugLink: https://bugs.launchpad.net/bugs/1357928 Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-09-03ASoC: max98090: Add recovery for PLL lock failureJarkko Nikula
All MAX98090 input clocks MCLK, LRCLK and BCLK must be running and stable before powering on the codec in slave mode. Otherwise the PLL may not lock to LRCLK causing silence in playback and capture. How often that happens is somewhat hardware and clock configuration specific. Now if wanting to follow strictly this clocks must be active before powering the codec on requirement we should have a notification from DAI driver to codec driver when clocks are activated and take codec out of shutdown only after that. Plus take care of possible active bypass paths. However, when PLL unlock occurs, MAX98090 asserts the PLL Unlock Flag which can be configured as an IRQ source. This allows to workaround around the issue by toggling the codec power shortly in case of PLL lock failure. In order to prevent needlessly toggling codec power in case of short PLL unlocks at the beginning of stream this patch implements delayed activation for PLL unlock interrupt. Then workaround is run only when the PLL doesn't lock at all. Power toggling workaround for PLL unlock comes originally from Liam Girdwood <liam.r.girdwood@linux.intel.com> and delayed activation from me.

2014-09-03ALSA: pcm: Uninline snd_pcm_stream_lock() and _unlock()Takashi Iwai
The previous commit for the non-atomic PCM ops added more codes to snd_pcm_stream_lock() and its variants. Since they are inlined functions, it resulted in a significant code size bloat. For reducing the size bloat, this patch changes the inline functions to the normal function calls. The export of rwlock and rwsem are removed as well, since they are referred only in pcm_native.c now. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-09-03ALSA: pcm: Allow nonatomic trigger operationsTakashi Iwai
Currently, many PCM operations are performed in a critical section protected by spinlock, typically the trigger and pointer callbacks are assumed to be atomic. This is basically because some trigger action (e.g. PCM stop after drain or xrun) is done in the interrupt handler. If a driver runs in a threaded irq, however, this doesn't have to be atomic. And many devices want to handle trigger in a non-atomic context due to lengthy communications. This patch tries all PCM calls operational in non-atomic context. What it does is very simple: replaces the substream spinlock with the corresponding substream mutex when pcm->nonatomic flag is set. The driver that wants to use the non-atomic PCM ops just needs to set the flag and keep the rest as is. (Of course, it must not handle any PCM ops in irq context.) Note that the code doesn't check whether it's atomic-safe or not, but trust in 100% that the driver sets pcm->nonatomic correctly. One possible problem is the case where linked PCM substreams have inconsistent nonatomic states. For avoiding this, snd_pcm_link() returns an error if one tries to link an inconsistent PCM substream.

Commit ff795d614bfa ("ASoC: ab8500: Convert register I/O to regmap") initially converted the ab8500 CODEC driver to use regmap rather than legacy ASoC IO. This was reverted though in commit 63e6d43bf80d ("ASoC: ab8500: Revert to using custom I/O functions") since the inital conversion was not working properly. This was presumebly because the SOC_SINGLE_XR_SX controls, which are used by this driver, did not properly support regmap at that point. This has since been fixed in commit 6137a5ca326d ("ASoC: Prepare SOC_SINGLE_XR_SX controls for regmap"). So revert back to regmap again.

Generally, if the audio data in big endian format, which will be using the bytes reversion, Here this can only be used to bits reversion. So using the 'lsb-first' instead of 'big-endian-data' can make the code to be readable easier and more easy to understand what this property is used to do.
