Merge tag 'rtc-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linuxHEADmaster
Pull RTC updates from Alexandre Belloni: "Support for a new RTC in an existing driver and all the drivers exposing clocks using the common clock framework have been converted to determine_rate(). Summary: Subsystem: - Convert drivers exposing a clock from round_rate() to determine_rate() Drivers: - ds1307: oscillator stop flag handling for ds1341 - pcf85063: add support for RV8063" * tag 'rtc-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (34 commits) rtc: ds1685: Update Joshua Kinard's email address. rtc: rv3032: convert from round_rate() to determine_rate() rtc: rv3028: convert from round_rate() to determine_rate() rtc: pcf8563: convert from round_rate() to determine_rate() rtc: pcf85063: convert from round_rate() to determine_rate() rtc: nct3018y: convert from round_rate() to determine_rate() rtc: max31335: convert from round_rate() to determine_rate() rtc: m41t80: convert from round_rate() to determine_rate() rtc: hym8563: convert from round_rate() to determine_rate() rtc: ds1307: convert from round_rate() to determine_rate() rtc: rv3028: fix incorrect maximum clock rate handling rtc: pcf8563: fix incorrect maximum clock rate handling rtc: pcf85063: fix incorrect maximum clock rate handling rtc: nct3018y: fix incorrect maximum clock rate handling rtc: hym8563: fix incorrect maximum clock rate handling rtc: ds1307: fix incorrect maximum clock rate handling rtc: pcf85063: scope pcf85063_config structures rtc: Optimize calculations in rtc_time64_to_tm() dt-bindings: rtc: amlogic,a4-rtc: Add compatible string for C3 rtc: ds1307: handle oscillator stop flag (OSF) for ds1341 ...
