The DryIce-based RTC supports alarms that trigger an interrupt. Add an option to configure this interrupt as a wakeup source that wakes the system up from standby mode. Signed-off-by: Martin Kaiser <martin@xxxxxxxxx> --- v2: - unconditionally declare rtc-imxdi as wakeup source - use dev_pm_set_wake_irq instead of manually coding suspend and resume simple test (no need to configure the wakeup source via sysfs any more) [root@board ]# rtcwake -s 3 -m mem wakeup from "mem" at Fri Apr 30 09:23:52 2021 ...
