2009-09-08ASoC: au1x: PSC-AC97 bugfixesManuel Lauss
This patch fixes the following bugs: - only reprogram bitdepth if it has changed since last call to hw_params. - add locking inside ac97_read/write functions: When reprogramming sample depth, the ac97 unit has to be disabled, which should not be done in the middle of codec register accesses. - retry timed-out codec register accesses. - wait for status bits to set/clear when starting/stopping various functional blocks; very important after reenabling AC97 unit else sound may be distorted (e.g. high-pitch noise in 1kHz sine wave). - clear fifos before/after starting/stopping RX/TX. - longer timeouts waiting for PSC/AC97 ready after cold reset with certain codecs this can take ridiculous amounts of time. Run-tested on various Au1200 platforms with various codecs. Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-28ALSA: Add missing SNDRV_PCM_INFO_BATCH flag to some driversTakashi Iwai
Added SNDRV_PCM_INFO_BATCH flag to PCM info field of some drivers that really don't give the precise pointer value. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-04ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao
Considering the fact that most cpu_dai or codec_dai are using a same 'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better made a pointer instead, to make sharing easier and code a bit cleaner. The patch below is rather preliminary since the asoc tree is being actively developed, and this touches almost every piece of code, (and possibly many others in development need to be changed as well). Building of all codecs are OK, yet to every SoC, I didn't test that.

2009-01-19ASoC: Staticise PCM operations tablesMark Brown
The PCM operations tables are not exported directly but are instead included in the platform structure so should be declared static. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2008-12-09ASoC: Register platform driversMark Brown
This is done at modprobe time, mirroring current behaviour, except for mpc5200_psc_i2s where we do registration at the same time as we register with soc-of-simple. Since the core currently ignores registration this has no practical impact. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-09ASoC: Register platform DAIsMark Brown
Register all platform DAIs with the core. In line with current behaviour this is done at module probe time rather than when the devices are probed (since currently that only happens as the entire ASoC card is registered except for those drivers that currently implement some kind of hotplug). Since the core currently ignores DAI registration this has no practical effect. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-03ASoC: Remove platform device from DAI suspend and resume operationsMark Brown
None of the DAIs use it except s3c2412-i2s which only uses it for dev_() printouts. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-11-24ASoC: Remove DAI type informationMark Brown
DAI type information is only ever used within ASoC in order to special case AC97 and for diagnostic purposes. Since modern CPUs and codecs support multi function DAIs which can be configured for several modes it is more trouble than it's worth to maintain anything other than a flag identifying AC97 DAIs so remove the type field and replace it with an ac97_control flag.

2008-11-21ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown
Liam Girdwood's ASoC v2 work avoids having two different ops structures for DAIs by merging the members of struct snd_soc_ops into struct snd_soc_dai_ops, allowing per DAI configuration for everything. Backport this change. This paves the way for future work allowing any combination of DAIs to be connected rather than having fixed purpose CODEC and CPU DAIs and only allowing CODEC<->CPU interconnections.

2008-11-21ASoC: Rename snd_soc_card to snd_soc_machineMark Brown
One of the issues with the ASoC v1 API which has been addressed in the ASoC v2 work that Liam Girdwood has done is that the ALSA card provided by ASoC is distributed around the ASoC structures. For example, machine wide data such as the struct snd_card are maintained as part of the CODEC data structure, preventing the use of multiple codecs. This has been addressed by refactoring the data structures so that all the data for the ALSA card is contained in a single structure snd_soc_card which replaces the existing snd_soc_machine and snd_soc_device. Begin the process of backporting this by renaming struct snd_soc_machine to struct snd_soc_card, better reflecting its function and bringing it closer to standard ALSA terminology.
