-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>;
- dvdd-supply = <&reg_3v3>;
- iovdd-supply = <&reg_1v8>;

+description:
+ The Texas Instruments PCM186x family are multi-channel audio ADCs
+ that support both I2C and SPI control interfaces, selected by
+ pin strapping. These devices include on-chip programmable gain
+ amplifiers and support differential or single-ended analog inputs.
