Merge tag 'rtc-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni: "A lot of unnecessary code removal in here that ends up decreasing the number of lines in the subsystem. The ds1343 and ds1347 drivers got cleaned up. The rest are the usual fixes and new features. Subsystem: - fix warnings and errors with make W=1 - UIE are now disabled while setting the RTC time - UIE are now disallowed when the RTC time is not set. Drivers: - remove unecessary .remove callbacks - Set RTC range for cros-ec, ds1343, ds1347, m41t80, s35390a, vt8500 - Use devm_platform_ioremap_resource where applicable - rv3028: add clock out support" * tag 'rtc-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (81 commits) rtc: Fix Kconfig indentation rtc: xgene: Remove unused struct device in struct xgene_rtc_dev rtc: sun6i: Remove struct device from sun6i_rtc_dev rtc: st-lpc: Remove struct resource from struct st_rtc rtc: pcf8523: Remove struct pcf8523 rtc: meson: remove redundant assignment to variable retries rtc: v3020: remove set but unused variable rtc: tegra: remove set but unused variable rtc: pm8xxx: update kerneldoc for struct pm8xxx_rtc rtc: m41t80: remove excess kerneldoc rtc: ds1685: fix build error with make W=1 rtc: ds1685: remove set but unused variables rtc: ds1374: remove unused variable rtc: sysfs: fix hctosys_show kerneldoc rtc: interface: fix kerneldoc comments rtc: msm6242: Remove unneeded msm6242_set()/msm6242_clear() functions rtc: msm6242: Fix reading of 10-hour digit rtc: tps65910: allow using RTC without alarm interrupt rtc: fsl-ftm-alarm: remove select FSL_RCPM and default y from Kconfig rtc: pcf8563: Constify clkout_rates ...
