Re: [PATCH 4.4.y] ASoC: rsnd: adg :: AUDIO-CLKOUTn asynchronizes support

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

 



Dear Greg,

Renesas Rcar sound ADG has 2 modes: synchronous (BRGA) and asynchronous (BRGB).
Before this patch, ADG use synchronous mode.
This patch supports asynchronous via device tree ("clkout-lr-asynchronous"). It's optional.

AUDIO-CLKOUTn synchronizes with L/R clock is now default behavior.
