+JZ4740 and similar SoCs real-time clock driver
+
+Required properties:
+
+- compatible: One of:
+ - "ingenic,jz4740-rtc" - for use with the JZ4740 SoC
+ - "ingenic,jz4780-rtc" - for use with the JZ4780 SoC
+- reg: Address range of rtc register set
+- interrupts: IRQ number for the alarm interrupt
+- interrupt-parent: phandle of the interrupt controller
+- clocks: phandle to the "rtc" clock
+- clock-names: must be "rtc"
+
+Optional properties:
+- system-power-controller: To use this component as the
+ system power controller
+- reset-pin-assert-time: Reset pin low-level assertion time
+ after wakeup (default 60ms; range 0-125ms if RTC clock at
+ 32 kHz)
+- min-wakeup-pin-assert-time: Minimum wakeup pin assertion time
+ (default 100ms; range 0-2s if RTC clock at 32 kHz)
+
+Example:
+
+rtc@10003000 {
+ compatible = "ingenic,jz4740-rtc";
+ reg = <0x10003000 0x3F>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <32>;
+
+ clocks = <&rtc_clock>;
+ clock-names = "rtc";
+
+ system-power-controller;
+ reset-pin-assert-time = <60>;
+ min-wakeup-pin-assert-time = <100>;
+};
