2009-06-25Merge branch 'for-2.6.31' into for-2.6.32Mark Brown
2009-06-13ASoC: Add suspend and resume callbacks to Wolfson CODEC driversMark Brown
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-06-13ASoC: Automatically control WM8903 sloping stopband filterMark Brown
For best performance the DAC sloping stopband filter should be enabled below 24kHz and not enabled above that so remove the user visible control for this and do it autonomously in the driver. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-06-12ASoC: Remove odd bit clock ratios for WM8903Mark Brown
These are not supported since performance can not be guaranteed when they are in use. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@kernel.org

This is now handled by symmetric_rates. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-22ASoC: Actively manage the DC servo for WM8903Mark Brown
Save a little extra power by enabling the DC servo offset correction for the output channels only when the relevant channels are enabled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-22ASoC: Optimise configuration of WM8903 DC servoMark Brown
Modify the default startup sequence in the chip to set the DC servo dither level for optimal performance. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-22ASoC: Support CLK_DSP in WM8903Mark Brown
CLK_DSP provides a master clock for the DAC and ADC related functionality on the device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-04-16ASoC: Request shared rates for WM8903Mark Brown
It has a shared LRCLK. 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.

2009-02-18ASoC: Add device init/exit annotations to new-style Wolfson CODEC driversMark Brown
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-01-27ASoC: Push the codec runtime storage into the card structureMark Brown
This is a further stage on the road to refactoring away the ASoC platform device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-01-09ASoC: cleanup duplicated code.Ian Molton
Many codec drivers were implementing cookie-cutter copies of the function that adds kcontrols to the codec. This patch moves this code to a common function snd_soc_add_controls() in soc-core.c and updates all drivers using copies of this function to use the new common version.

2008-12-10ASoC: Stop WM8903 SYSCLK when suspendingMark Brown
This will save some additional power. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-10ASoC: Convert WM8903 driver to register at I2C probe timeMark Brown
The driver now registers the codec and DAI when probed as an I2C device. Also convert the driver to use a single dynamic allocation to simplify error handling. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-10ASoC: Work around warnings from some build environmentsMark Brown
BUG() should be marked as not returning but for at least some configurations (including some widely deployed compilers) that's either not happening or being forgotten by the compiler. Add some extra return statements to the affected paths. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-10ALSA: ASoC - Fix wrong section typesTakashi Iwai
The module init entries should be __init instead of __devinit. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-12-09ASoC: Register non-AC97 codec DAIsMark Brown
Currently this is done at module probe time since ASoC ties in codec device probe to the instantiation of the entire ASoC device. Subsequent patches will refactor the codec drivers to handle probing separately. Note that the core does not yet use this information. AC97 is special since the codec is controlled over the AC97 link but we want to give the machine driver a chance to set up the system before trying to instantiate since it may need to do configuration before the AC97 link will operate Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2008-12-01ASoC: Rename snd_soc_register_card() to snd_soc_init_card()Mark Brown
Currently ASoC card initialisation is completed by a function called snd_soc_register_card(). As part of the work to allow independant registration of cards, codecs and machines in ASoC v2 a new function of the same name has been added so rename the existing function to facilitate the merge of v2.

2008-12-01Revert "ALSA: soc - Fix compile warnings in wm8903.c"Takashi Iwai
This reverts commit 9171e5e6a20a9cd4992ff9c7cbee13c6fdf7b0b1. I can't reproduce the compile warnings any more. The warnings might be some weird cross-compiling set up. Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.
