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- reg: Address range of rtc register set
12- interrupts: rtc timer, alarm interrupts in order
13- interrupt-parent: phandle for the interrupt controller
14
15Optional properties:
16- system-power-controller: whether the rtc is controlling the system power
17 through pmic_power_en
18
19Example:
20
21rtc@1c23000 {
22 compatible = "ti,da830-rtc";
23 reg = <0x23000 0x1000>;
24 interrupts = <19
25 19>;
26 interrupt-parent = <&intc>;
27 system-power-controller;
28};
