| | | | | | | | | | | | | | | | | | | | | | Driver does not use module parameter for nowayout, so it need to statically initialize status variable of the watchdog_device based on CONFIG_WATCHDOG_NOWAYOUT.

| * rtc: ingenic: Reset regulator register in probePaul Cercueil2020-05-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The regulator register specifies how many input clock cycles (minus one) are contained in one tick of the 1 Hz clock. Since this register can contain bogus values after the system boots, it needs to be reset in the probe register, otherwise the RTC may count way to slow or way too fast.

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 ...

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>
