[PATCH v7] ASoC: cs53l30: Add codec driver support for Cirrus CS53L30

From: Nicolin Chen
Date: Wed May 25 2016 - 15:39:16 EST

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.

Signed-off-by: Nicolin Chen <nicoleotsuka@xxxxxxxxx>

Changelog:
v6->v7
* Added vendor prefixes to properties in DT binding doc
* Updated the property names in the driver accordingly
* Added two required power supplies in the example
* Refined two dev_err messages
* Re-ordered the header files
* Revised the commit log
v5->v6
* Added clock controls
* Reconstructed bitfield macros and improved coding style
* Fixed some misuses of regmap_update_bits()
* Added TLV volume controls to replace enums for preamplifier
* Added micbias level in DT instead of exposing to user-space
* Simplified SDOUTx controls by removing cs53l30_asp_sdout_event()
(Still be able to use set_tristate() instead)
* Removed useless header files and sort the rest alphabetically
* Registered runtime pm functions to the driver
* Added regulator controls (VA and VP)
* Added writeable register function for regmap
* Merged two ASP dais
* Added TDM support
* Added a simple introduction in commit log

+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>;
+};
