Commit Message

Joseph Jang May 3, 2024, 1:41 a.m. UTC 
Some platforms do not support WAKEUP service by default, we use a shell
script to check the absence of alarm content in /proc/driver/rtc.

The script will validate /proc/driver/rtc when it is not empty and then
check if could find alarm content in it according to the rtc wakealarm
is supported or not.

Requires commit 101ca8d05913b ("rtc: efi: Enable SET/GET WAKEUP services
as optional")
