-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>;
-};
