Merge tag 'pinctrl-v4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 

Pull pin control fixes from Linus Walleij:
 "Here is a set of pin control fixes for the v4.6 series.

  A bit bigger than what I hoped for, but all fixes are confined to
  drivers, a few of them also targeted to stable.

  Summary:

   - On Super-H PFC (Renesas) controllers: only use dummies on legacy
     systems.  This fixes a serious ethernet regression on a Renesas
     board.
   - Pistachio: Fix errors in the pin table.
   - Allwinner SunXi: fix the external interrupts to work.
   - Intel: fix so the high level interrupts start working, and fix a
     spurious interrupt issue.
   - Qualcomm ipq4019: fix the number of GPIOs provided (bump to 100),
     correct register offsets and handle GPIO mode properly.
   - Revert the revert on the revert so that Xway has a .to_irq()
     callback again.
   - Minor fixes to errorpaths and debug info.
   - A MAINTAINERS update"
