On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.

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.
|
|
- reg: Address range of rtc register set
|
|
- interrupts: rtc timer, alarm interrupts in order
|
|
- interrupt-parent: phandle for the interrupt controller
|
|
|
|
Example:
|
|
|
|
rtc@1c23000 {
|
|
compatible = "ti,da830-rtc";
|
|
reg = <0x23000 0x1000>;
|
|
interrupts = <19
|
|
19>;
|
|
interrupt-parent = <&intc>;
|
|
};
