The TAS2552 can receive its 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 select and configure the PLL and PDM reference clocks.
