   1 TI Real Time Clock
   2
   3 Required properties:
   4 - compatible:
   5         - "ti,da830-rtc"  - for RTC IP used similar to that on DA8xx SoC family.
   6         - "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
   7                             This RTC IP has special WAKE-EN Register to enable
   8                             Wakeup generation for event Alarm. It can also be
   9                             used to control an external PMIC via the
  10                             pmic_power_en pin.
  11 - reg: Address range of rtc register set
  12 - interrupts: rtc timer, alarm interrupts in order
  13 - interrupt-parent: phandle for the interrupt controller
  14
  15 Optional properties:
  16 - system-power-controller: whether the rtc is controlling the system power
  17   through pmic_power_en
  18
  19 Example:
  20
  21 rtc@1c23000 {
  22         compatible = "ti,da830-rtc";
  23         reg = <0x23000 0x1000>;
  24         interrupts = <19
  25                       19>;
  26         interrupt-parent = <&intc>;
  27         system-power-controller;
  28 };
