[PATCH 0/8] rtc: isl12022: battery backup voltage and clock support

[Rasmus Villemoes]

The current handling of the low-battery bits in the status register is
wrong. The first six patches fix that and implement proper support for
RTC_VL_READ.

The last two patches allow describing the isl12022 as a clock
provider, for now just as a fixed 32kHz clock. They are also
tangentially related to the backup battery, in that when the isl12022
is not used as a clock source, one can save some power consumption in
battery mode by setting the FOx bits to 0.
