All the drivers that have been modified for this now are ready for the end of times (whether it happens in 2033, 2038, 2106, 2127 or even 4052). There is also a single new driver and the usual fixes and features. Summary: Subsystem: - The rtc_time_to_tm and rtc_tm_to_time wrappers have finally been removed and only the 64bit version remain. - hctosys now works with drivers compiled as modules New driver: - MediaTek MT2712 SoC based RTC Drivers: - set range for 88pm860x, au1xxx, cpcap, da9052, davinci, ds1305, ds1374, mcp5121, pl030, pl031, pm8xxx, puv3, sa1100, sirfsoc, starfire, sun6i - ds1307: DS1388 oscillator failure detection and watchdog support - jz4740: JZ4760 support - pcf85063: clock out pin support - sun6i: external 32k oscillator is now optional, the range is now handled by the core, providing a solution for 2034" * tag 'rtc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (87 commits) rtc: ds1307: check for failed memory allocation on wdt rtc: class: remove redundant assignment to variable err rtc: remove rtc_time_to_tm and rtc_tm_to_time rtc: sun6i: let the core handle rtc range rtc: sun6i: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: ds1307: add support for watchdog timer on ds1388 rtc: da9052: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: da9052: set range rtc: da9052: convert to devm_rtc_allocate_device rtc: imx-sc: Align imx sc msg structs to 4 rtc: fsl-ftm-alarm: report alarm to core rtc: pcf85063: Add pcf85063 clkout control to common clock framework rtc: make definitions in include/uapi/linux/rtc.h actually useful for user space rtc: class: avoid unnecessary lookup in hctosys dt-bindings: rtc: Convert and update jz4740-rtc doc to YAML rtc: jz4740: Rename vendor-specific DT properties rtc: jz4740: Add support for JZ4760 SoC rtc: class: support hctosys from modular RTC drivers rtc: pm8xxx: clear alarm register when alarm is not enabled rtc: omap: drop unused dt-bindings header ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WENR feature (set a magic value to enable RTC registers read-write) first appeared on the JZ4760; the JZ4780 came much later. Since it would be dangerous to specify a newer SoC's compatible string as the fallback of an older SoC's compatible string, we add support for the "ingenic,jz4760-rtc" compatible string in the driver. This will permit to support the JZ4770 by having: compatible = "ingenic,jz4770-rtc", "ingenic,jz4760-rtc"; Instead of doing: compatible = "ingenic,jz4770-rtc", "ingenic,jz4780-rtc"; Signed-off-by: Paul Cercueil <paul@crapouillou.net> Link: https://lore.kernel.org/r/20200311182318.22154-1-paul@crapouillou.net Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

| * rtc: sun6i: Make external 32k oscillator optionalJernej Skrabec2020-03-161-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards, like OrangePi PC2 (H5), OrangePi Plus 2E (H3) and Tanix TX6 (H6) don't have external 32kHz oscillator. Till H6, it didn't really matter if external oscillator was enabled because HW detected error and fall back to internal one. H6 has same functionality but it's the first SoC which have "auto switch bypass" bit documented and always enabled in driver. This prevents RTC to work correctly if external crystal is not present on board. There are other side effects - all peripherals which depends on this clock also don't work (HDMI CEC for example). Make clocks property optional. If it is present, select external oscillator. If not, stay on internal.

| | | | | | | | | | | | | | | | | | | | The PL031 and ST v1 RTC are 32bit seconds counters. STv2 is a BCD RTC apparently going from 0000 to 9999, hopefully handling the leap days properly until then.

| | | | | | | | | | | | | | | | | | The datasheet states that 4052 is the maximum value for year. However, the mpc5121 read_time and set_time function abuse the target time register instead of using the broken down time so it is limited to 2106.
