ASoC: tas2552: Correct PDM configuration register bit definitions The PDM clock can be selected via bit0-1. PDM_DATA_ES bit is at bit2. The code were trying to select BCLK as PDM reference clock but instead it was selecting PLL and set the DATA_ES bit to 1. Selecting the PLL output as reference clock as default does make sense, but the driver should not change the PDM data edge.
