ST M41T80 family of RTC and compatible



Required properties:

- compatible: should be one of:

	"st,m41t62",

	"st,m41t65",

	"st,m41t80",

	"st,m41t81",

	"st,m41t81s",

	"st,m41t82",

	"st,m41t83",

	"st,m41t84",

	"st,m41t85",

	"st,m41t87",

	"microcrystal,rv4162",

- reg: I2C bus address of the device



Optional properties:

- interrupt-parent: phandle for the interrupt controller.

- interrupts: rtc alarm interrupt.

- clock-output-names: From common clock binding to override the default output

                      clock name

- wakeup-source: Enables wake up of host system on alarm



Example:

	rtc@68 {

		compatible = "st,m41t80";

		reg = <0x68>;

		interrupt-parent = <&UIC0>;

		interrupts = <0x9 0x8>;

	};
