-Everest ES8316 audio CODEC
-
-This device supports both I2C and SPI.
-
-Required properties:
-
-  - compatible  : should be "everest,es8316"
-  - reg : the I2C address of the device for I2C
-
-Optional properties:
-
-  - clocks : a list of phandle, should contain entries for clock-names
-  - clock-names : should include as follows:
-         "mclk" : master clock (MCLK) of the device
-
-Example:
-
-es8316: codec@11 {
-	compatible = "everest,es8316";
-	reg = <0x11>;
-	clocks = <&clks 10>;
-	clock-names = "mclk";
-};
