Merge tag 'gpio-v4.19-1' 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 v4.19 kernel cycle.

  I don't know if anything in particular stands out. Maybe the Aspeed
  coprocessor thing from Benji: Aspeed is doing baseboard management
  chips (BMC's) for servers etc.

  These Aspeed's are ARM processors that exist inside (I guess) Intel
  servers, and they are moving forward to using mainline Linux in those.
  This is one of the pieces of the puzzle to achive that. They are doing
  OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/

  Summary:

  Core changes:

   - Add a new API for explicitly naming GPIO consumers, when needed.

   - Don't let userspace set values on input lines. While we do not
     think anyone would do this crazy thing we better plug the hole
     before someone uses it and think it's a nifty feature.

   - Avoid calling chip->request() for unused GPIOs.

  New drivers/subdrivers:

   - The Mediatek MT7621 is supported which is a big win for OpenWRT and
     similar router distributions using this chip, as it seems every
     major router manufacturer on the planet has made products using
     this chip: https://wikidevi.com/wiki/MediaTek_MT7621

   - The Tegra 194 is now supported.

   - The IT87 driver now supports IT8786E and IT8718F super-IO chips.

   - Add support for Rockchip RK3328 in the syscon GPIO driver.

  Driver changes:

   - Handle the get/set_multiple() properly on MMIO chips with inverted
     direction registers. We didn't have this problem until a new chip
     appear that has get/set registers AND inverted direction bits, OK
     now we handle it.

   - A patch series making more error codes percolate upward properly
     for different errors on gpiochip_lock_as_irq().

   - Get/set multiple for the OMAP driver, accelerating these multiple
     line operations if possible.

   - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
     lines need to be grabbed by a co-processor for doing automated
     tasks, sometimes they are available as GPIO lines. By adding an
     explicit API in this driver we make it possible for the two line
     consumers to coexist. (This work was made available on the
     ib-aspeed branch, which may be appearing in other pull requests.)

   - Implemented .get_direction() and open drain in the SCH311x driver.

   - Continuing cleanup of included headers in GPIO drivers"
