| CS53L30 audio CODEC |
| |
| Required properties: |
| |
| - compatible : "cirrus,cs53l30" |
| |
| - reg : the I2C address of the device |
| |
| - VA-supply, VP-supply : power supplies for the device, |
| as covered in Documentation/devicetree/bindings/regulator/regulator.txt. |
| |
| Optional properties: |
| |
| - reset-gpios : a GPIO spec for the reset pin. |
| |
| - mute-gpios : a GPIO spec for the MUTE pin. The active state can be either |
| GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled |
| by the driver automatically. |
| |
| - cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin. |
| 0 = Hi-Z |
| 1 = 1.80 V |
| 2 = 2.75 V |
| |
| - cirrus,use-sdout2 : This is a boolean property. If present, it indicates |
| the hardware design connects both SDOUT1 and SDOUT2 |
| pins to output data. Otherwise, it indicates that |
| only SDOUT1 is connected for data output. |
| * CS53l30 supports 4-channel data output in the same |
| * frame using two different ways: |
| * 1) Normal I2S mode on two data pins -- each SDOUT |
| * carries 2-channel data in the same time. |
| * 2) TDM mode on one single data pin -- SDOUT1 carries |
| * 4-channel data per frame. |
| |
| Example: |
| |
| codec: cs53l30@48 { |
| compatible = "cirrus,cs53l30"; |
| reg = <0x48>; |
| reset-gpios = <&gpio 54 0>; |
| VA-supply = <&cs53l30_va>; |
| VP-supply = <&cs53l30_vp>; |
| }; |
