Hi Linus,
this is the bulk of GPIO changes for the v4.12 kernel cycle.
Nothing really exciting goes on here this time, the most exciting
for me is the same as for pin control: realtime is advancing thanks
so Julia Cartwright.
There are some ACPI-induced changes in other subsystems, and
those are ACKed by the maintainers.
Details in the signed tag as usual.
Please pull it in!
Yours,
Linus Walleij

gpio: f7188x: Add a missing break (2017-04-28 10:09:16 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v4.12 kernel cycle:
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.
