* ASoC: Factor out I/O for Wolfson 8 bit data 16 bit register CODECsMark Brown2009-08-031-203/+116

* ASoC: Automatically manage WM8900 sloping stopband filterMark Brown2009-06-131-1/+12
| | | | | | | | | 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>

* ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao2009-03-041-7/+9
| | | | | | | | | | | | | | | | 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.

* ASoC: Push the codec runtime storage into the card structureMark Brown2009-01-271-4/+4
| | | | | | | This is a further stage on the road to refactoring away the ASoC platform device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: cleanup duplicated code.Ian Molton2009-01-091-17/+2
| | | | | | | | | | | | | | | 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.

* ASoC: Convert WM8900 to do more work at I2C probe timeMark Brown2008-12-101-78/+81
| | | | | | | | | | | Redo the instantiation of the WM8900 to do most of the initialisation work when the I2C driver probes rather than when the ASoC device is instantiated, registering the codec with the ASoC core when done. Also move all dynamic allocations into a single kmalloc() to simplify error handling and rename the I2C driver to make output more sensible.

* ALSA: ASoC - Fix wrong section typesTakashi Iwai2008-12-101-1/+1

* ASoC: Convert WM8900 to allow registration by machine codeMark Brown2008-12-091-77/+20
| | | | | | | | This makes use of the support for delayed DAI registration to allow the WM8900 I2C device to be registered by general platform/architecture code rather than as part of the ASoC device probe. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Register non-AC97 codec DAIsMark Brown2008-12-091-0/+12
| | | | | | | | | | | | | | 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>
* ASoC: Rename snd_soc_register_card() to snd_soc_init_card()Mark Brown2008-12-011-1/+1
| | | | | | | | | | 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.

* ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown2008-11-211-3/+2
| | | | | | | | | | | | | 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.
