+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.
