Merge tag 'rtc-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "A new driver this cycle is making the bulk of the changes and the
  rx8010 driver has been rework to use the modern APIs.

  Summary:

  Subsystem:
   - new generic DT properties: aux-voltage-chargeable,
     trickle-voltage-millivolt

  New driver:
   - Microcrystal RV-3032

  Drivers:
   - ds1307: use aux-voltage-chargeable
   - r9701, rx8010: modernization of the driver
   - rv3028: fix clock output, trickle resistor values, RAM
     configuration registers"
