Merge tag 'rtc-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"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.
New drivers:
- Sunplus SP7021 RTC
- Nintendo GameCube, Wii and Wii U RTC
Driver updates:
- cmos: refactor UIP handling and presence check, fix century
- rs5c372: offset correction support, report low voltage
- rv8803: Epson RX8804 support"
