Move AKM CODECs to multi-component model.

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

o Make CODEC driver a platform device (non MFD codecs only) 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 ak4535: set_bias_level() has to perform mute IO directly rather than via ak4535 mute since struct codec no longer contains dai.

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 device (non MFD codecs only) 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 device (non MFD codecs only) 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.

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 device (non MFD codecs only) 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 cx20442: tty hangup now performed in codec remove() rather than machine remove() since codec device is not now available at machine remove().

Moved Wolfson WM87xx CODECs to multi-component model.

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

o Make CODEC driver a platform device (non MFD codecs only) 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 wm8753: dai mode configuration now modifies private data to store mode.

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 device (non MFD codecs only) 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 wm8960: codec device no longer has set_bias(), so func moved to private data.

Move to 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 device (non MFD codecs only) 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 wm8994: set_fll() needs to be accessed from both codec and dai device context, so wrapper added to acces from dai context.

Move Wolfson AudioPlus CODECs to multi-component model.

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

o Make CODEC driver a platform device (non MFD codecs only) 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.
