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
15Optional properties:
16- system-power-controller: whether the rtc is controlling the system power
17  through pmic_power_en
18- clocks: Any internal or external clocks feeding in to rtc
19- clock-names: Corresponding names of the clocks
20- pinctrl-0: a phandle pointing to the pin settings for the device
21- pinctrl-names: should be "default"
22
23Optional subnodes:
24- generic pinctrl node
25
26Required pinctrl subnodes properties:
27- pins - Names of ext_wakeup pins to configure
28
29Optional pinctrl subnodes properties:
30- input-enable - Enables ext_wakeup
31- ti,active-high - Set input active high (by default active low)
