Subject: [PATCH] soc: pcm3168a: Add DT binding to force clock consumer mode
|
|
|
|
ASoC cannot configure the codec correctly when the ADC and DAC share clock
|
|
lines and one of them is the clock producer. Add a DT binding that
|
|
overrides ASoC and forces the component into clock consumer mode.
