-Real Time Clock driver for:
-  - 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>;
-		epson,vdet-disable;
-		trickle-diode-disable;
-	};
