[GIT PULL] RTC for 5.10

[Alexandre Belloni]

Hello Linus,

Here is the RTC pull request for 5.10. A new driver this cycle is making
the bulk of the changes and the rx8010 driver has been rework to use the
modern APIs.

The following changes since commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5:

  Linux 5.9-rc1 (2020-08-16 13:04:57 -0700)

RTC for 5.10

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
