17tas2552 can receive it's reference clock via MCLK, BCLK, IVCLKIN pin or use the
18internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL, the PDM
19reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
20For system integration the dt-bindings/sound/tas2552.h header file provides
21defined values to selct and configure the PLL and PDM reference clocks.
