| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible : "cirrus,cs53l30" |
| 6 | |
| 7 | - reg : the I2C address of the device |
| 8 | |
| 9 | - VA-supply, VP-supply : power supplies for the device, |
| 10 | as covered in Documentation/devicetree/bindings/regulator/regulator.txt. |
| 11 | |
| 12 | Optional 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 either |
| 17 | GPIO_ACTIVE_HIGH or GPIO_ACTIVE_LOW, which would be handled |
| 18 | by the driver automatically. |
| 19 | |
| 20 | - cirrus,micbias-lvl : Set the output voltage level on the MICBIAS Pin. |
| 21 | 0 = Hi-Z |
| 22 | 1 = 1.80 V |
| 23 | 2 = 2.75 V |
| 24 | |
| 25 | - cirrus,use-sdout2 : This is a boolean property. If present, it indicates |
| 26 | the hardware design connects both SDOUT1 and SDOUT2 |
| 27 | pins to output data. Otherwise, it indicates that |
| 28 | only SDOUT1 is connected for data output. |
| 29 | * CS53l30 supports 4-channel data output in the same |
| 30 | * frame using two different ways: |
| 31 | * 1) Normal I2S mode on two data pins -- each SDOUT |
| 32 | * carries 2-channel data in the same time. |
| 33 | * 2) TDM mode on one single data pin -- SDOUT1 carries |
| 34 | * 4-channel data per frame. |
| 35 | |
| 36 | Example: |
| 37 | |
| 38 | codec: 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 | }; |
