[alsa-devel] [RFC 10/16] ASoC: multi-component - Wolfson wm8900, 8903, 8904 and 8955 CODECs
Liam Girdwood
lrg at slimlogic.co.uk
Fri Jun 25 19:52:57 CEST 2010
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 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.
