| * sun6i Real Time Clock |
| |
| RTC controller for the Allwinner A31 |
| |
| Required properties: |
| - compatible : Should be "allwinner,sun6i-a31-rtc" |
| - reg : physical base address of the controller and length of |
| memory mapped region. |
| - interrupts : IRQ lines for the RTC alarm 0 and alarm 1, in that order. |
| |
| Required properties for new device trees |
| - clocks : phandle to the 32kHz external oscillator |
| - clock-output-names : names of the LOSC and its external output clocks created |
| - #clock-cells : must be equals to 1. The RTC provides two clocks: the |
| LOSC and its external output, with index 0 and 1 |
| respectively. |
| |
| Example: |
| |
| rtc: rtc@01f00000 { |
| compatible = "allwinner,sun6i-a31-rtc"; |
| reg = <0x01f00000 0x54>; |
| interrupts = <0 40 4>, <0 41 4>; |
| clock-output-names = "osc32k", "osc32k-out"; |
| clocks = <&ext_osc32k>; |
| #clock-cells = <1>; |
| }; |
