Merge tag 'rtc-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni: "Most of the changes are a rework of the cmos driver by Rafael and fixes for issues found using static checkers. The removal of a driver leads to a reduction of the number of LOC of the subsystem. Removed driver: - davinci Updates: - convert i2c drivers to .probe_new - fix spelling mistakes and duplicated words in comments - cmos: rework wake setup and ACPI event handling - cros-ec: Limit RTC alarm range to fix alarmtimer - ds1347: fix century register handling - efi: wakeup support - isl12022: temperature sensor support - pcf85063: fix read_alarm and clkout - pcf8523: use stop bit to detect invalid time - pcf8563: use RTC_FEATURE_ALARM - snvs: be more flexible on LPSRT reads - many static checker fixes" * tag 'rtc-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (48 commits) rtc: ds1742: use devm_platform_get_and_ioremap_resource() rtc: mxc_v2: Add missing clk_disable_unprepare() rtc: rs5c313: correct some spelling mistakes rtc: at91rm9200: Fix syntax errors in comments rtc: remove duplicated words in comments rtc: rv3028: Use IRQ flags obtained from device tree if available rtc: ds1307: use sysfs_emit() to instead of scnprintf() rtc: isl12026: drop obsolete dependency on COMPILE_TEST dt-bindings: rtc: m41t80: Convert text schema to YAML one rtc: pcf85063: fix pcf85063_clkout_control rtc: rx6110: fix warning with !OF rtc: rk808: reduce 'struct rk808' usage rtc: msc313: Fix function prototype mismatch in msc313_rtc_probe() dt-bindings: rtc: convert rtc-meson.txt to dt-schema rtc: pic32: Move devm_rtc_allocate_device earlier in pic32_rtc_probe() rtc: st-lpc: Add missing clk_disable_unprepare in st_rtc_probe() rtc: pcf85063: Fix reading alarm rtc: pcf8523: fix for stop bit rtc: efi: Add wakeup support rtc: pcf8563: clear RTC_FEATURE_ALARM if no irq ...
