Core changes
- Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
This was a much discussed change. It affects use cases where people
write drivers that might or might not be using GPIO resources.
I have decided that this is the lesser evil right now.
- Make gpiod_count() behave consistently across different hardware
descriptions.
- Fix the syntax around open drain/open source to not infer active
high/low semantics.
New drivers
- A new single-register fixed-direction framework driver for hardware
that have lines controlled by a single register that just work in
one direction (out or in), including IRQ support.
- Support the Fintek F71889A GPIO SuperIO controller.
- Support the National NI 169445 MMIO GPIO.
- Support for the X-Gene derivative of the DWC GPIO controller
- Support for the Rohm BD9571MWV-M PMIC GPIO controller.
- Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
and replace both the Gemini and the Moxa ART custom drivers with
this driver.
Driver improvements
- A whole slew of drivers have their spinlocks chaned to raw spinlocks
as they provide irqchips, and thus we are progressing on realtime
compliance.
- Use devm_irq_alloc_descs() in a slew of drivers, getting managed
resources.
- Support for the embedded PWM controller inside the MVEBU driver.
- Debounce, open source and open drain support for the Aspeed driver.
- Misc smaller fixes like spelling and syntax and whatnot.
