Merge tag 'pinctrl-v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control fixes from Linus Walleij:
 "Here is an overdue pull request for pin control fixes, the most
  prominent feature is to make Intel Chromebooks (and I suspect any
  other Cherryview-based Intel thing) happy again, which we really want
  to see.

  There is a patch hitting drivers/firmware/* that I was uncertain to
  who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
  review tags on it and I trust them both 100% to do the right thing for
  Intel platform drivers.

  Summary:

   - Make a few Intel Chromebooks with Cherryview DMI firmware work
     smoothly.

   - A fix for some bogus allocations in the generic group management
     code.

   - Some GPIO descriptor lookup table stubs. Merged through the pin
     control tree for administrative reasons.

   - Revert the "bi-directional" and "output-enable" generic properties:
     we need more discussions around this. It seems other SoCs are using
     input/output gate enablement and these terms are not correct.

   - Fix mux and drive strength atomically in the MXS driver.

   - Fix the SPDIF function on sunxi A83T.

   - OF table terminators and other small fixes"
