Subject: [PATCH v3 0/8] Add MAX77714 PMIC minimal driver (RTC and watchdog only)
Date: Thu, 11 Nov 2021 23:58:44 +0100	[thread overview]
Message-ID: <20211111225852.3128201-1-luca@lucaceresoli.net> (raw)

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 and 8 add: dt bindings, mfd driver, watchdog driver and rtc
driver.

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

Luca

  rtc: max77686: convert comments to kernel-doc format
  rtc: max77686: rename day-of-month defines
  rtc: max77686: remove unused code to read in 12-hour mode
  dt-bindings: mfd: add Maxim MAX77714 PMIC
  mfd: max77714: Add driver for Maxim MAX77714 PMIC
  watchdog: Kconfig: fix help text indentation
  watchdog: max77714: add driver for the watchdog in the MAX77714 PMIC
  rtc: max77686: add MAX77714 support
