| 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>; |
| }; |
