RTC controller for the Allwinner A10/A20
Required properties:
- compatible : Should be "allwinner,sun4i-rtc" or "allwinner,sun7i-a20-rtc"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: IRQ line for the RTC.
Example:
rtc: rtc@01c20d00 {
compatible = "allwinner,sun4i-rtc";
reg = <0x01c20d00 0x20>;
interrupts = <24>;
};
