-Texas Instruments PCM186x Universal Audio ADC
-
-These devices support both I2C and SPI (configured with pin strapping
-on the board).
-
-Required properties:
-
- - compatible : "ti,pcm1862",
-                "ti,pcm1863",
-                "ti,pcm1864",
-                "ti,pcm1865"
-
- - reg : The I2C address of the device for I2C, the chip select
-         number for SPI.
-
- - avdd-supply: Analog core power supply (3.3v)
- - dvdd-supply: Digital core power supply
- - iovdd-supply: Digital IO power supply
-        See regulator/regulator.txt for more information
-
-CODEC input pins:
- * VINL1
- * VINR1
- * VINL2
- * VINR2
- * VINL3
- * VINR3
- * VINL4
- * VINR4
-
-The pins can be used in referring sound node's audio-routing property.
-
-Example:
-
-	pcm186x: audio-codec@4a {
-		compatible = "ti,pcm1865";
-		reg = <0x4a>;
-
-		avdd-supply = <&reg_3v3_analog>;

It's better to list out the actual changes instead of only making
developers go to v1 to see which feedback you actually brought into
