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" * tag 'rtc-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (26 commits) rtc: nuvoton: Compatible with NCT3015Y-R and NCT3018Y-R rtc: da9063: Use dev_err_probe() rtc: da9063: Use device_get_match_data() rtc: da9063: Make IRQ as optional rtc: max31335: Fix comparison in max31335_volatile_reg() rtc: max31335: use regmap_update_bits_check rtc: max31335: remove unecessary locking rtc: max31335: add driver support dt-bindings: rtc: max31335: add max31335 bindings rtc: rv8803: add wakeup-source support rtc: ac100: remove misuses of kernel-doc rtc: class: Remove usage of the deprecated ida_simple_xx() API rtc: MAINTAINERS: drop Alessandro Zummo rtc: ma35d1: remove hardcoded UIE support dt-bindings: rtc: qcom-pm8xxx: fix inconsistent example rtc: rv8803: Add power management support rtc: ds3232: avoid unused-const-variable warning rtc: lpc24xx: add missing dependency rtc: tps6594: Add driver for TPS6594 RTC rtc: Add driver for Nuvoton ma35d1 rtc controller ...
