3Required properties:
4- compatible: should be one of:
5 "st,m41t62",
6 "st,m41t65",
7 "st,m41t80",
8 "st,m41t81",
9 "st,m41t81s",

13 "st,m41t85",
14 "st,m41t87",
15 "microcrystal,rv4162",
16- reg: I2C bus address of the device
17
18Optional properties:
19- interrupts: rtc alarm interrupt.
20- clock-output-names: From common clock binding to override the default output
21 clock name
22- wakeup-source: Enables wake up of host system on alarm

24Example:
25 rtc@68 {
26 compatible = "st,m41t80";
27 reg = <0x68>;
28 interrupt-parent = <&UIC0>;
29 interrupts = <0x9 0x8>;
30 };
