dt-bindings: rtc: Add bindings for m41t80 and compatibles
The ST M41T80 family of RTC are not trivial devices, document them. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Rob Herring <robh@kernel.org>

+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>;
+ };
