X-Git-Tag: v4.9.8~3567^2~80^2~11^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=48edaa4b4fb6e75b890942394f0d0c2571d5c90d;p=platform%2Fkernel%2Flinux-rpi3.git

ASoC: rt5645: Add the device tree parser

Modify the RT5645 driver to parse platform data from device tree. This is
missing from previous patch in sound/soc/codecs/rt5645.c, that was present
in v3.
