Fix up trivial conflict in arch/arm/kernel/signal.c. It was due to the TIF_NOTIFY_RESUME addition in commit d0420c83f ("KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures") and follow-ups.
2009-07-09[ARM] 5596/1: at91sam9g20-ek: Register WM8731 in board fileMark Brown
The WM8731 driver has been updated to allow registration via normal device model methods rather than from within the ASoC driver probe so update the AT91SAM9G20-EK to make use of this.

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.

2009-02-18ASoC: 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.

2009-02-18ASoC: Improve diagnostics for AT91SAM9G20-EK probeMark Brown

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>
2008-11-21ASoC: 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.
