-* Xilinx Zynq Ultrascale+ MPSoC Real Time Clock
-
-RTC controller for the Xilinx Zynq MPSoC Real Time Clock
-Separate IRQ lines for seconds and alarm
-
-Required properties:
-- compatible: Should be "xlnx,zynqmp-rtc"
-- reg: Physical base address of the controller and length
-       of memory mapped region.
-- interrupts: IRQ lines for the RTC.
-- interrupt-names: interrupt line names eg. "sec" "alarm"
-
-Optional:
-- calibration: calibration value for 1 sec period which will
-		be programmed directly to calibration register
-
-Example:
-rtc: rtc@...60000 {
-	compatible = "xlnx,zynqmp-rtc";
-	reg = <0x0 0xffa60000 0x100>;
-	interrupt-parent = <&gic>;
-	interrupts = <0 26 4>, <0 27 4>;
-	interrupt-names = "alarm", "sec";
-	calibration = <0x198233>;
