-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
-- 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-ms: Reset pin low-level assertion
-  time after wakeup (default 60ms; range 0-125ms if RTC clock
-  at 32 kHz)
-- min-wakeup-pin-assert-time-ms: Minimum wakeup pin assertion
-  time (default 100ms; range 0-2s if RTC clock at 32 kHz)
-
-Example:
-
-rtc@10003000 {
-	compatible = "ingenic,jz4740-rtc";

-	reset-pin-assert-time-ms = <60>;
-	min-wakeup-pin-assert-time-ms = <100>;
