dt-bindings: es8328: convert to DT schema format 



Convert the binding to DT schema format. Note, that "IPVDD-supply"
got fixed to be "HPVDD-supply" during the conversion. This was
obviously a typo in the old binding. The old binding example, DT
files, chip datasheet and Linux driver use HPVDD.

Everest ES8328 audio CODEC



This device supports both I2C and SPI.



Required properties:



  - compatible  : Should be "everest,es8328" or "everest,es8388"

  - DVDD-supply : Regulator providing digital core supply voltage 1.8 - 3.6V

  - AVDD-supply : Regulator providing analog supply voltage 3.3V

  - PVDD-supply : Regulator providing digital IO supply voltage 1.8 - 3.6V

  - IPVDD-supply : Regulator providing analog output voltage 3.3V

  - clocks : A 22.5792 or 11.2896 MHz clock

  - reg : the I2C address of the device for I2C, the chip select number for SPI



Pins on the device (for linking into audio routes):



  * LOUT1

  * LOUT2

  * ROUT1

  * ROUT2

  * LINPUT1

  * RINPUT1

  * LINPUT2

  * RINPUT2

  * Mic Bias





Example:



codec: es8328@11 {

	compatible = "everest,es8328";

	DVDD-supply = <&reg_3p3v>;

	AVDD-supply = <&reg_3p3v>;

	PVDD-supply = <&reg_3p3v>;

	HPVDD-supply = <&reg_3p3v>;

	clocks = <&clks 169>;

	reg = <0x11>;

};
