|
||
|
|
|
||
|
|
- compatible: "ti,pcm3168a"
|
||
|
|
|
||
|
|
- clocks : Contains an entry for each entry in clock-names
|
||
|
|
|
||
|
|
- clock-names : Includes the following entries:
|
||
|
|
"scki" The system clock
|
||
|
|
|
||
|
|

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
|
||
|
|
|
