[alsa-devel] [PATCH 13/17] ASoC: multi-component - Wolfson WM8978, 8988 and 8994 CODECs
Liam Girdwood
lrg at slimlogic.co.uk
Wed Aug 11 01:03:04 CEST 2010
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 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 wm8994: set_fll() needs to be accessed from both codec and dai
device context, so wrapper added to acces from dai context.
