[GIT PULL] RTC for 5.16
From: Alexandre Belloni
Date: Thu Nov 11 2021 - 17:54:15 EST
Hello Linus,
Here is the RTC subsystem pull request for v5.16. This includes new
ioctls to get and set parameters and in particular the backup switch
mode that is needed for some RTCs to actually enable the backup voltage
(and have a useful RTC).
The same interface can also be used to get the actual features supported
by the RTC so userspace has a better way than trying and failing.
The following changes since commit 6880fa6c56601bb8ed59df6c30fd390cc5f6dd8f:
Linux 5.15-rc1 (2021-09-12 16:28:37 -0700)

----------------------------------------------------------------
RTC for 5.16
Subsystem:
- Add new ioctl to get and set extra RTC parameters, this includes backup
switch mode
- Expose available features to userspace, in particular, when alarmas have a
resolution of one minute instead of a second.
- Let the core handle those alarms with a minute resolution
New driver:
- MSTAR MSC313 RTC
Drivers:
- Add SPI ID table where necessary
- Add BSM support for rv3028, rv3032 and pcf8523
- s3c: set RTC range
- rx8025: set range, implement .set_offset and .read_offset
