Merge tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "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"
