+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
+
+Examples:
