[PATCH 0/2] rtc: ab-eoz9: fix the undervoltage handling

[Maxime Chevallier]

The AB EOZ9 can report if there are undervoltage conditions encountered
while the RTC is maintaining the date and time. This is useful when a
device is stored for a long amount of time without being used, to know
how reliable the reported date and time are at reboot.

Patch 1 reworks the user report of undervoltages by checking the lowest
threshold first.

Patch 2 makes so that we don't fail the temperature readout, as when the
system is currently running, the RTC battery should be at a nominal
voltage. Temperature-related undervoltage reports are about what
happened while the system was down, and not about the current state of
the power supply.
