  - Epson RX8900

  - Micro Crystal rv8803



Required properties:

- compatible: should be: "microcrystal,rv8803" or "epson,rx8900"

- reg : the I2C address of the device for I2C



Optional properties:

- epson,vdet-disable : boolean, if present will disable voltage detector.

  Should be set if no backup battery is used.

- trickle-diode-disable : boolean, if present will disable internal trickle

  charger diode



Example:



	rtc: rtc@32 {

		compatible = "epson,rx8900"

		reg = <0x32>;
