+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>;
+	};
