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>;
|
|
};
