+PCM512x audio CODECs
+
+These devices support both I2C and SPI (configured with pin strapping
+on the board).
+
+Required properties:
+
+ - compatible : One of "ti,pcm5121", "ti,pcm5122", "ti,pcm5141" or
+ "ti,pcm5142"
+
+ - reg : the I2C address of the device for I2C, the chip select
+ number for SPI.
+
+ - AVDD-supply, DVDD-supply, and CPVDD-supply : power supplies for the
+ device, as covered in bindings/regulator/regulator.txt
+
+Optional properties:
+
+ - clocks : A clock specifier for the clock connected as SCLK. If this
+ is absent the device will be configured to clock from BCLK. If pll-in
+ and pll-out are specified in addition to a clock, the device is
+ configured to accept clock input on a specified gpio pin.
+
+ - pll-in, pll-out : gpio pins used to connect the pll using <1>
+ through <6>. The device will be configured for clock input on the
+ given pll-in pin and PLL output on the given pll-out pin. An
+ external connection from the pll-out pin to the SCLK pin is assumed.
+
+Examples:
+
+ pcm5122: pcm5122@4c {
+ compatible = "ti,pcm5122";
+ reg = <0x4c>;
+
+ AVDD-supply = <&reg_3v3_analog>;
+ DVDD-supply = <&reg_1v8>;
+ CPVDD-supply = <&reg_3v3>;
+ };
+
+
+ pcm5142: pcm5142@4c {
+ compatible = "ti,pcm5142";
+ reg = <0x4c>;
+
+ AVDD-supply = <&reg_3v3_analog>;
+ DVDD-supply = <&reg_1v8>;
+ CPVDD-supply = <&reg_3v3>;
+
+ clocks = <&sck>;
+ pll-in = <3>;
+ pll-out = <6>;
+ };
