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 {
|
|
|
|
...
