ASoC: cs53l30: Add codec driver support for Cirrus CS53L30 



CS53L30 is a Quad-Channel ADC from Cirrus Logic with an I2S/TDM DAI.
So this patch adds a codec driver for CS53L30 that includes 4-channel
24-bit recording and TDM mode supports.

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.



  - 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.



Example:



codec: cs53l30@48 {

	compatible = "cirrus,cs53l30";

	reg = <0x48>;

	reset-gpios = <&gpio 54 0>;

	VA-supply = <&cs53l30_va>;

	VP-supply = <&cs53l30_vp>;

};
