Hi maintainers,
In this v4 patch series include following:
- Fix the issue that rtc alarm interrupt triggered befor driver probe is not cleared
- Correct the value written into PM8xxx_RTC_ALARM_CLEAR register in trigger function
Regarding the issue "Fix the issue that rtc alarm interrupt triggered befor driver probe is not cleared":
- Issue describtion as following
If the alarm is triggered before the driver gets probed, the alarm interrupt
will be missed and it won't be detected, and the stale alarm settings will
be still retained because of not being cleared.
- Issue reproduce step:
(1) set the alarm and poweroff the device
(2) alarm happens and the device boots
(3) poweroff the device again
(4) alarm irq not be cleard, device boots again
Regarding "Correct the value written into PM8xxx_RTC_ALARM_CLEAR"
- Writing 1 to the register is expected to clear the fired alarm
register. In patch v2, the value written to the register in the
trigger function is incorrectly written as 0. So correct the value
to 1.
