    2 
    3 This device supports both I2C and SPI.
    4 
    5 Required properties:
    6 
    7   - compatible  : Should be "everest,es8328" or "everest,es8388"
    8   - DVDD-supply : Regulator providing digital core supply voltage 1.8 - 3.6V
    9   - AVDD-supply : Regulator providing analog supply voltage 3.3V
   10   - PVDD-supply : Regulator providing digital IO supply voltage 1.8 - 3.6V
   11   - IPVDD-supply : Regulator providing analog output voltage 3.3V
   12   - clocks : A 22.5792 or 11.2896 MHz clock
   13   - reg : the I2C address of the device for I2C, the chip select number for SPI
   14
