5Required properties:
6
7  - compatible: "ti,pcm3168a"
8
9  - clocks : Contains an entry for each entry in clock-names
10
11  - clock-names : Includes the following entries:
12	"scki"	The system clock
13
14  - VDD1-supply : Digital power supply regulator 1 (+3.3V)

26For required properties on SPI/I2C, consult SPI/I2C device tree documentation
27
28Optional properties:
29
30  - reset-gpios : Optional reset gpio line connected to RST pin of the codec.
31		  The RST line is low active:
32		  RST = low: device power-down
33		  RST = high: device is enabled
