-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
