ingenic,jz4740-rtc.txt
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";
reg = <0x10003000 0x40>;
interrupt-parent = <&intc>;
interrupts = <32>;
clocks = <&rtc_clock>;
clock-names = "rtc";
system-power-controller;
reset-pin-assert-time-ms = <60>;
min-wakeup-pin-assert-time-ms = <100>;
};
