[alsa-devel] [RFC 09/16] ASoC: multi-component - Wolfson WM87xx CODECs
Liam Girdwood
lrg at slimlogic.co.uk
Fri Jun 25 19:52:56 CEST 2010
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.
