| 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 { |
| |
| ... |
| |
