Subject: [GIT PULL] RTC changes for 5.17

Hello Linus,

Here is the RTC subsystem pull request for v5.17.

Two new drivers this cycle and a significant rework of the CMOS driver
make the bulk of the changes.
I also carry powerpc changes with the agreement of Michael.

The following changes since commit fa55b7dcdc43c1aa1ba12bca9d2dd4318c2a0dbf:

  Linux 5.16-rc1 (2021-11-14 13:56:52 -0800)

are available in the Git repository at:
