+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:
+- 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
+
+Optional child node:
+- clock: Provide this if the square wave pin is used as boot-enabled fixed clock.
+
+Example:
+ rtc@68 {
+ compatible = "st,m41t80";
+ reg = <0x68>;
+ interrupt-parent = <&UIC0>;
+ interrupts = <0x9 0x8>;
+
+ clock {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <32768>;
+ };
+ };
