| 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 | |
| - interrupt-parent: phandle for the interrupt controller | |
| 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; | |
| }; | |
| }; |
