1CS53L30 audio CODEC2 3Required properties:4 5 - compatible : "cirrus,cs53l30"6 7 - reg : the I2C address of the device8 9 - VA-supply, VP-supply : power supplies for the device,10 as covered in Documentation/devicetree/bindings/regulator/regulator.txt.11 12Optional properties:13 14 - reset-gpios : a GPIO spec for the reset pin.15 16 - mute-gpios : a GPIO spec for the MUTE pin. The active state can be either17 GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled18 by the driver automatically.19 20 - cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin.21 0 = Hi-Z22 1 = 1.80 V23 2 = 2.75 V24 25 - cirrus,use-sdout2 : This is a boolean property. If present, it indicates26 the hardware design connects both SDOUT1 and SDOUT227 pins to output data. Otherwise, it indicates that28 only SDOUT1 is connected for data output.29 * CS53l30 supports 4-channel data output in the same30 * frame using two different ways:31 * 1) Normal I2S mode on two data pins -- each SDOUT32 * carries 2-channel data in the same time.33 * 2) TDM mode on one single data pin -- SDOUT1 carries34 * 4-channel data per frame.35 36Example:37 38codec: cs53l30@48 {39 compatible = "cirrus,cs53l30";40 reg = <0x48>;41 reset-gpios = <&gpio 54 0>;42 VA-supply = <&cs53l30_va>;43 VP-supply = <&cs53l30_vp>;44};45
