ASoC: dt-bindings: ti,pcm3168a: Convert to json-schema
Convert the Texas Instruments PCM3168A Audio Codec Device Tree binding documentation to json-schema. Add missing properties. Drop unneeded pinctrl properties from example.

Texas Instruments pcm3168a DT bindings
|
||||
|
||||
This driver supports both SPI and I2C bus access for this codec
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: "ti,pcm3168a"
|
||||
|
||||
- clocks : Contains an entry for each entry in clock-names
|
||||
|
||||
- clock-names : Includes the following entries:
|
||||
"scki" The system clock
|
||||
|
||||
- VDD1-supply : Digital power supply regulator 1 (+3.3V)
|
||||
|
||||
- VDD2-supply : Digital power supply regulator 2 (+3.3V)
|
||||
|
||||
- VCCAD1-supply : ADC power supply regulator 1 (+5V)
|
||||
|
||||
- VCCAD2-supply : ADC power supply regulator 2 (+5V)
|
||||
|
||||
- VCCDA1-supply : DAC power supply regulator 1 (+5V)
|
||||
|
||||
- VCCDA2-supply : DAC power supply regulator 2 (+5V)
|
||||
|
||||
For required properties on SPI/I2C, consult SPI/I2C device tree documentation
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios : Optional reset gpio line connected to RST pin of the codec.
|
||||
The RST line is low active:
|
||||
RST = low: device power-down
|
||||
RST = high: device is enabled
|
||||
|
||||
Examples:
|
||||
|
||||
i2c0: i2c0@0 {
|
||||
|
||||
...
|
||||
|
||||
pcm3168a: audio-codec@44 {
