    1 Cadence Real Time Clock
    2 
    3 The Cadence RTC controller with date, time and alarm capabilities.
    4 The alarm may wake the system from low-power state.
    5 
    6 Required properties:
    7 - compatible: Should be "cdns,rtc-r109v3"
    8 - reg: Specifies base physical address and size of the register area.
    9 - interrupts: A single interrupt specifier.
   10 - clocks: Must contain two entries:
   11         - pclk: APB registers clock
   12         - ref_clk: reference 1Hz or 100Hz clock, depending on IP configuration
   13         See ../clocks/clock-bindings.txt for details.
   14 
   15 Example:
   16         rtc0: rtc@fd080000 {
   17                 compatible = "cdns,rtc-r109v3";
   18                 reg = <0xfd080000 0x1000>;
   19 
   20                 clock-names = "pclk", "ref_clk";
   21                 clocks = <&sysclock>, <&refclock>;
   22 
   23                 interrupt-parent = <&gic>;
   24                 interrupts = <0 6 IRQ_TYPE_LEVEL_HIGH>;
   25         };
