Linus Torvalds 6de4c691ea This is the bulk of GPIO changes for the v4.19 kernel cycle:
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.

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
