* Alphascale asm9260 SoC Real Time Clock
Required properties:
- compatible: Should be "alphascale,asm9260-rtc"
- reg: Physical base address of the controller and length
of memory mapped region.
- interrupts: IRQ line for the RTC.
- clocks: Reference to the clock entry.
- clock-names: should contain:
* "ahb" for the SoC RTC clock
Example:
rtc0: rtc@800a0000 {
compatible = "alphascale,asm9260-rtc";
reg = <0x800a0000 0x100>;
clocks = <&acc CLKID_AHB_RTC>;
clock-names = "ahb";
interrupts = <2>;
};
