Pull RTC updates from Alexandre Belloni: "A huge series from me this cycle. I went through many drivers to set the date and time range supported by the RTC which helps solving HW limitation when the time comes (as early as next year for some). This time, I focused on drivers using .set_mms and .set_mmss64, allowing me to remove those callbacks. About a third of the patches got reviews, I actually own the RTCs and I tested another third and the remaining one are unlikely to cause any issues. Other than that, a single new driver and the usual fixes here and there. Summary: Subsystem: - set_mmss and set_mmss64 rtc_ops removal - Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900 - Use SPDX identifier for the core - validate upper bound of tm->tm_year New driver: - Aspeed BMC SoC RTC Drivers: - abx80x: use rtc_add_group - ds3232: nvram support - pcf85063: add alarm, nvram, offset correction and microcrystal rv8263 support - x1205: add of_match_table - Use set_time instead of set_mms/set_mmss64 for: ab3100, coh901331, digicolor, ds1672, ds2404, ep93xx, imxdi, jz4740, lpc32xx, mc13xxx, mxc, pcap, stmp3xxx, test, wm831x, xgene. - Set RTC range for: ab3100, at91sam9, coh901331, da9063, digicolor, dm355evm, ds1672, ds2404, ep39xx, goldfish, imxdi, jz4740, lpc32xx, mc13xxx, mv, mxc, omap, pcap, pcf85063, pcf85363, ps3, sh, stmp3xxx, sun4v, tegra, wm831x, xgene. - Switch to rtc_time64_to_tm/rtc_tm_to_time64 for the driver that properly set the RTC range. - Use dev_get_drvdata instead of multiple indirections" * tag 'rtc-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (177 commits) rtc: snvs: Use __maybe_unused instead of #if CONFIG_PM_SLEEP rtc: imxdi: remove unused variable rtc: drop set_mms and set_mmss64 rtc: pcap: convert to SPDX identifier rtc: pcap: use .set_time rtc: pcap: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: pcap: set range rtc: digicolor: convert to SPDX identifier rtc: digicolor: use .set_time rtc: digicolor: set range rtc: digicolor: fix possible race condition rtc: jz4740: convert to SPDX identifier rtc: jz4740: rework invalid time detection rtc: jz4740: use dev_pm_set_wake_irq() to simplify code rtc: jz4740: use .set_time rtc: jz4740: remove useless check rtc: jz4740: switch to rtc_time64_to_tm/rtc_tm_to_time64 rtc: jz4740: set range rtc: 88pm860x: prevent use-after-free on device remove rtc: Use dev_get_drvdata() ...
