14description: >
15  The TAS2552 can receive its reference clock via MCLK, BCLK, IVCLKIN pin or
16  use the internal 1.8MHz. This CLKIN is used by the PLL. In addition to PLL,
17  the PDM reference clock is also selectable: PLL, IVCLKIN, BCLK or MCLK.
18
19  For system integration the dt-bindings/sound/tas2552.h header file provides
20  defined values to select and configure the PLL and PDM reference clocks.
