[alsa-devel] [PATCH 06/14] ASoC: multi-component - Renasas SuperH Platform
Liam Girdwood
lrg at slimlogic.co.uk
Wed Aug 11 10:46:25 CEST 2010
Update the Renasas SuperH platform and machines to new multi-component model.
This patch changes the machine drivers for multi-component as follows :-
o Removed socdev
o Each DAI link entry now contains platform and codec fields.
o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.
This patch also changes the DAI and platform DAM drivers as follows :-
o Each platform DAI and platform DMA driver is a kernel device and can
have platform data.
o DAI and Platform DMA drivers have private data accessors.
Other notable changes required for multi-component support:-
o Decoupled platform DMA and DAI drivers.
o Added extern struct siu_info *siu_i2s_data (ideally this should be passed
around the sui_dai_ops rather than being a global).
