[alsa-devel] [PATCH 3/3] ASoC: sh: fsi: Add snd_soc_dai_set_fmt support
Kuninori Morimoto

Wed Jan 12 07:24:45 CET 2011
This patch add snd_soc_dai_ops :: set_fmt to FSI driver and
select master/slave clock mode by snd_soc_dai_set_fmt on
fsi-xxx.c instead of platform infomation code.
This patch remove fsi_is_master function which is no longer needed.
