Merge tag 'rtc-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"There are three new drivers this cycle. Also the cmos driver is
getting fixes for longstanding wakeup issues on AMD.
New drivers:
- Analog Devices MAX31335
- Nuvoton ma35d1
- Texas Instrument TPS6594 PMIC RTC
Drivers:
- cmos: use ACPI alarm instead of HPET on recent AMD platforms
- nuvoton: add NCT3015Y-R and NCT3018Y-R support
- rv8803: proper suspend/resume and wakeup-source support"
