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.
