[PATCH v2 0/9] Add MAX77714 PMIC minimal driver (RTC and watchdog only)

From: Luca Ceresoli
Date: Tue Oct 19 2021 - 10:59:39 EST


Hi,

this series adds minimal drivers for the Maxim Semiconductor MAX77714
(https://www.maximintegrated.com/en/products/power/power-management-ics/MAX77714.html).
Only RTC and watchdog are implemented by these patches.

All implemented functionality is tested and working: RTC read/write,
watchdog start/stop/ping/set_timeout.

Patches 1-4 + 7 are trivial cleanups to the max77686 drivers and can
probably be applied easily.

Patches 5, 6, 8 and 9 add: dt bindings, mfd driver, watchdog driver and rtc
driver.

Changes in v2:
- fixed all issues reported on v1 patches
- added patch 7 ("watchdog: Kconfig: fix help text indentation")
- additional minor improvements
