It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. allOf: - $ref: dai-common.yaml# properties: compatible: enum: - cirrus,cs42l43 reg: maxItems: 1 vdd-p-supply: description: Power supply for the high voltage interface. vdd-a-supply: description: Power supply for internal analog circuits. vdd-d-supply: description: Power supply for internal digital circuits.
