1* Xilinx Zynq Ultrascale+ MPSoC Real Time Clock 2 3RTC controller for the Xilinx Zynq MPSoC Real Time Clock 4Separate IRQ lines for seconds and alarm 5 6Required properties: 7- compatible: Should be "xlnx,zynqmp-rtc" 8- reg: Physical base address of the controller and length 9 of memory mapped region. 10- interrupts: IRQ lines for the RTC. 11- interrupt-names: interrupt line names eg. "sec" "alarm" 12 13Optional: 14- calibration: calibration value for 1 sec period which will 15 be programmed directly to calibration register 16 17Example: 18rtc: rtc@ffa60000 { 19 compatible = "xlnx,zynqmp-rtc"; 20 reg = <0x0 0xffa60000 0x100>; 21 interrupt-parent = <&gic>; 22 interrupts = <0 26 4>, <0 27 4>; 23 interrupt-names = "alarm", "sec"; 24 calibration = <0x198233>; 25}; 26
