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: 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>

2009-01-09ASoC: 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.

2008-12-09ASoC: 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.

2008-11-21ASoC: 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.

2008-08-25ALSA: ASoC: Fix double free and memory leak in many codec driversJean Delvare
Many SoC audio codec drivers have improper freeing of memory in error paths. * codec is allocated in the platform device probe function, but is not freed there in case of error. Instead it is freed in the i2c device probe function's error path. However the success or failure of both functions is not linked, so this could result in a double free (if the platform device is successfully probed, the i2c device probing fails and then the platform driver is unregistered.) * codec->private_data is allocated in many platform device probe functions but not freed in their error paths. This patch hopefully solves all these problems.

2008-05-19[ALSA] ASoC: Clarify API for bias configurationMark Brown
Currently the ASoC core configures the bias levels in the system using a callback on codecs and machines called 'dapm_event', passing it PCI style power levels as SNDRV_CTL_POWER_ constants. This is more obscure than it needs to be and has caused confusion to driver authors, especially given that DAPM is also performing power management. Address this by renaming the callback function to 'set_bias_level' and using constants explicitly representing the off, standby, pre-on and on states which DAPM transitions through. Also unexport the API for setting bias level: there are currently no in-tree users of this API other than the core itself and it is likely that the core would need to be extended to cater for any users.
