tas2552 can receive it's reference clock via MCLK, BCLK, IVCLKIN pin or use the

internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM

reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.

For system integration the dt-bindings/sound/tas2552.h header file provides

defined values to selct and configure the PLL and PDM reference clocks.
