Subject: [PATCH 0/8] Add MAX77714 PMIC minimal driver (RTC and watchdog only)
Date: Mon, 11 Oct 2021 17:56:07 +0200 [thread overview]
Message-ID: <20211011155615.257529-1-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.
Note! Something seems wrong in the interrupt management code. Due to the
fact that I'm not using interrupts on my hardware and since this is my
first addition of an MFD driver, I was unable to understand what is wrong
after studying the code for other MFD drivers. More details in reply to
patch 8. Advice would be greatly appreciated on this topic.
Except for that, all implemented functionality is tested and working: RTC
read/write, watchdog start/stop/ping/set_timeout.
The first 4 patches are trivial cleanups to the max77686 drivers and can
probably be applied easily.
Patches 5-8 add: dt bindings, mfd driver, watchdog driver and rtc driver.
