Hi,
this series adds minimal drivers for the Maxim Semiconductor MAX77714
(https://www.maximintegrated.com/en/products/power/power-m...).
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 1-3 + 6 are trivial cleanups to the max77686 drivers and Kconfig
indentation and can probably be applied easily.
Patches 4, 5, 7, 8 and 9 add: dt bindings, mfd driver, watchdog driver and
rtc driver.
Changes in v4:
- do not add a new wdog driver for MAX77714, extend the MAX77620 wdog
driver; this means removing v3 patch 7, now replaced by patches 7+8
- added review tags
Changes in v3:
- fixed all issues reported on v1 patches
- removed patch 1 of v2, already applied
("mfd: max77686: Correct tab-based alignment of register addresses")
Changes in v2:
- fixed all issues reported on v1 patches
- added patch 7 ("watchdog: Kconfig: fix help text indentation")
- additional minor improvements
