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>;
