1TI Real Time Clock
2
3Required 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	- "ti,am4372-rtc" - for RTC IP used similar to that on AM437X SoC family.
12- reg: Address range of rtc register set
13- interrupts: rtc timer, alarm interrupts in order
14- interrupt-parent: phandle for the interrupt controller
15
16Optional properties:
17- system-power-controller: whether the rtc is controlling the system power
18  through pmic_power_en
19- clocks: Any internal or external clocks feeding in to rtc
20- clock-names: Corresponding names of the clocks
21
22Example:
23
24rtc@1c23000 {
25	compatible = "ti,da830-rtc";
26	reg = <0x23000 0x1000>;
27	interrupts = <19
28		      19>;
29	interrupt-parent = <&intc>;
30	system-power-controller;
31	clocks = <&clk_32k_rtc>, <&clk_32768_ck>;
32	clock-names = "ext-clk", "int-clk";
33};
