1JZ4740 and similar SoCs real-time clock driver
2
3Required properties:
4
5- compatible: One of:
6  - "ingenic,jz4740-rtc" - for use with the JZ4740 SoC
7  - "ingenic,jz4780-rtc" - for use with the JZ4780 SoC
8- reg: Address range of rtc register set
9- interrupts: IRQ number for the alarm interrupt
10- clocks: phandle to the "rtc" clock
11- clock-names: must be "rtc"
12
13Optional properties:
14- system-power-controller: To use this component as the
15  system power controller
16- reset-pin-assert-time-ms: Reset pin low-level assertion
17  time after wakeup (default 60ms; range 0-125ms if RTC clock
18  at 32 kHz)
19- min-wakeup-pin-assert-time-ms: Minimum wakeup pin assertion
20  time (default 100ms; range 0-2s if RTC clock at 32 kHz)
