[alsa-devel] [PATCH 0/3] ASoC: simple-card: cleanup simple-card daifmt
Hi Mark
These are cleanup patches for simple-card daifmt.
Kuninori Morimoto (3): ASoC: simple-card: tidyup use priv in parameter ASoC: simple-card: tidyup get dai_link/dai_props from priv ASoC: simple-card: add asoc_simple_card_parse_daifmt()

priv has many information about simple-card driver. Using it becomes easy to extend feature. This patch gets dev from priv as 1st step

Current daifmt setting method in simple-card driver is placed to many places, and using un-readable/confusable method. This patch adds new asoc_simple_card_parse_daifmt() and tidyup code.
