[PATCH v4 0/9] Add MAX77714 PMIC minimal driver (RTC and watchdog only)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 1-3 + 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
