[alsa-devel] [PATCH 1/4] ASoC: rsnd: call clk_prepare()/clk_enable() for AUDIO_CLKx

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

ADG can output AUDIO_CLKOUTx, and these are generated from
AUDIO_CLKx. Thus we need to call clk_prepare()/clk_enable()
for AUDIO_CLKx.
