[PATCH 08/15] ASoC: rsnd: rename clk to clkin

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

Current adg.c is usig "clk" as clock IN, but is using "clkout" for
clock OUT. This patch arranges "clk" to "clkin".

This is prepare for R-Car Gen4 support.
