0015 "microcrystal,rv4162",
0016 - reg: I2C bus address of the device
0017
0018 Optional properties:
0019 - interrupts: rtc alarm interrupt.
0020 - clock-output-names: From common clock binding to override the default output
0021 clock name
0022 - wakeup-source: Enables wake up of host system on alarm
0023
0024 Optional child node:
0025 - clock: Provide this if the square wave pin is used as boot-enabled fixed clock.

0027 Example:
0028 rtc@68 {
0029 compatible = "st,m41t80";
0030 reg = <0x68>;
0031 interrupt-parent = <&UIC0>;
0032 interrupts = <0x9 0x8>;
0033
0034 clock {
0035 compatible = "fixed-clock";
0036 #clock-cells = <0>;
0037 clock-frequency = <32768>;
0038 };
0039 };
