-TI Real Time Clock
-
-Required properties:
-- compatible:
- - "ti,da830-rtc" - for RTC IP used similar to that on DA8xx SoC family.
- - "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
- This RTC IP has special WAKE-EN Register to enable
- Wakeup generation for event Alarm. It can also be
- used to control an external PMIC via the
- pmic_power_en pin.
- - "ti,am4372-rtc" - for RTC IP used similar to that on AM437X SoC family.
-- reg: Address range of rtc register set
-- interrupts: rtc timer, alarm interrupts in order
-
-Optional properties:
-- system-power-controller: whether the rtc is controlling the system power
- through pmic_power_en
-- clocks: Any internal or external clocks feeding in to rtc
-- clock-names: Corresponding names of the clocks
-- pinctrl-0: a phandle pointing to the pin settings for the device
-- pinctrl-names: should be "default"
-
-Optional subnodes:
-- generic pinctrl node
-
-Required pinctrl subnodes properties:
-- pins - Names of ext_wakeup pins to configure
-
-Optional pinctrl subnodes properties:
-- input-enable - Enables ext_wakeup
-- ti,active-high - Set input active high (by default active low)
-
-Example:
-
-rtc@1c23000 {
- compatible = "ti,da830-rtc";
- reg = <0x23000 0x1000>;
- interrupts = <19
- 19>;
- interrupt-parent = <&intc>;
- system-power-controller;
- clocks = <&clk_32k_rtc>, <&clk_32768_ck>;
- clock-names = "ext-clk", "int-clk";
-
- pinctrl-0 = <&ext_wakeup>;
- pinctrl-names = "default";
-
- ext_wakeup: ext-wakeup {
- pins = "ext_wakeup0";
- input-enable;
- ti,active-high;
- };
-};
