Move codecs to multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Other required changes due to multi-component model :-

o cs42151 and cs4270: set_dai_sysclk() - we no longer change static _driver_ rates on clock changes (as the driver can be used by other cs24xx codec devices). The codec device rate is checked at hw_params() time.

Move TI CODECs to multi-component

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Other required changes due to multi-component model :-

o tlv320aic3x: no more "setup_data" from ASoC machine drivers, platform data must be set in one place only. Moved platform defs out into platorm header.

Moved generic codecs to multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Moved Wolfson WM85xx CODECs to multi-component model

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Moved to Wolfson CODECs multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Move Wolfson CODECs to multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Other required changes due to multi-component model :-

o wm8993: set_fll() needs to be accessed from both codec and dai device context, so wrapper added to acces from dai context.

Moved Wolfson WM90xx CODECs to multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.

Move Wolfson WM97xx AC97 CODECs to multi-component model.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.
