Subject: [PATCH] MLK-18898-1: ASoC: fsl_sai: select pinctrl state as function
|
|
of bitclock rate
|
|
|
|
Similar to DSD512 case we need a PCM pinctrl state option to map SAI BCLK
|
|
to codec MCLK pin. Given that bitclock rate is function of slots number and
|
|
slot width - pass bclk rate as parameter value from SAI driver.
