2009-07-08ASoC: Configure WM8731 SYSCLK at startup on AT91SAM9G20-EKMark Brown
The system clock is currently fixed by the driver and this avoids the need for us to handle errors with enabling and disabling MCLK (which was incorrect previously so this fixes bugs in error handling). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-08ASoC: Disable microphone input for AT91SAM9G20-EK by defaultMark Brown
As shipped the board does not have inputs but it is relatively straightforward to modify the board to hook them up so support is provided in the driver. When these modifications have not been made enabling the microphone stage can cause problems. Add an ifdef to disable this by default. Don't put it into Kconfig since users will have to get their soldering irons out to change things. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-08ASoC: Use CODEC as clock master on AT91SAM9G20-EKMark Brown
This simplifies the driver by removing the need to manually configure dividers within the CPU and improve audio performance by ensuring that the optimal phase relationships between the clocks in the system are maintained. Note that currently this means that for playback to work the Output Mixer HiFi switch must be enabled since otherwise CODEC will not generate the DAC clock.

2009-03-11ASoC: Merge dai_ops factor outMark Brown
Merge Eric Maio's patch to merge snd_soc_dai_ops out of line. Fixed merge issues and updated drivers, plus an issue with the ops for the two s3c2443 AC97 DAIs having been merged. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
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.

2009-03-04ASoC: wm8510 pll settingsJonas Andersson
When setting WM8510_MCLKDIV the pll was turned off. When setting pll frequency you got twice the expected freq, because the code calculated with postscaler of 8, but the hardware divide by 4.

2009-02-18ASoC: Refactor WM8731 device registrationMark Brown
Move the WM8731 driver to use a more standard device registration scheme where the device can be registered independantly of the ASoC probe. As a transition measure push the current manual code for registering the WM8731 into the individual machine driver probes. This allows separate patches to update the relevant architecture files with less risk of merge issues. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-02-18ASoC: Rename AT91SAMG20-EK for applicationsMark Brown
This is a bit more idiomatic and makes identifying a configuration based on the board type work better. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-02-18ASoC: Actively manage MCLK for AT91SAM9G20-EKMark Brown
We have software control of the MCLK for the WM8731 so save a bit of power by actively managing it within the machine driver, enabling it only while the codec is active. Once ASoC supports multiple boards and doesn't require the soc-audio device the initial clock setup should be pushed down into the arch/arm code but for now this reduces merge issues.

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>
2009-01-16ASoC: atmel_pcm: Remove non-existant headerBen Nizette
<mach/hardware.h> doesn't exist on AVR32 and therefore this driver won't build on that arch. AFAICT this driver doesn't actually use the content of that header so easiest just to remove it.

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>
2008-12-03ASoC: Remove device from platform suspend and resume operationsMark Brown
None of the platforms are actually using the SoC device so remove it (only atmel actually has a suspend method). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-02ASoC: Push platform registration down into the cardMark Brown
As part of the deprecation of snd_soc_device push the registration of the platform down into the card structure. 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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
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.

2008-10-31ASoC: Merge AT91 and AVR32 support into a single atmel architectureSedji Gaouaou
The Ateml AT91 and AVR32 SoC share common IP for audio and can share the same driver code using the atmel-ssc API provided for both architectures. Do this, creating a new unified atmel ASoC architecture to replace the previous at32 and at91 ones.
