 Bit Clock can be generated as follows:-
 
-BCLK = MCLK / x

-BCLK = LRC * x

-BCLK = LRC * Channels * Word Size
+- BCLK = MCLK / x, or

+- BCLK = LRC * Channels * Word Size
 
 This relationship depends on the codec or SoC CPU in particular. In general
 it is best to configure BCLK to the lowest possible speed (depending on your
