ASoC: dt-bindings: ti,pcm1862: convert to dtschema

Browse Source 
convert the Texas Instruments PCM186x Universal audio ADC bindings
to DT schema.

The PCM186x codec provides a single digital audio interface. Therefore
this binding adds a reference to dai-common.yaml and defines
'#sound-dai-cells = 0".

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.
CODEC input pins:
* VINL1
* VINR1
* VINL2
* VINR2
* VINL3
* VINR3
* VINL4
* VINR4
The pins can be used in referring sound node's audio-routing property.
