-* 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>;
-};
