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 signle data pin -- SDOUT1 carries
* 4-channel data per frame.
