This series has some patches for the rx8803 RTC handled by the rv8803 driver. These patches mostly improve the voltage loss handling in the rx8803. While the rv8803 resets its registers on voltage loss the rx8803 leaves registers in an undefined state after voltage loss. The patches are used here for a customer for quite a while, it's time to upstream them.
