Merge tag 'pinctrl-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is a calm cycle, not much happened this time around: not even
  much incremental development. Some three new drivers, that is all.

  No core changes.

  New drivers:

   - NXP (ex Freescale) i.MX 8QM driver.

   - NXP (ex Freescale) i.MX 8MM driver.

   - AT91 SAM9X60 subdriver.

  Improvements:

   - Support for external interrups (EINT) on Mediatek virtual GPIOs.

   - Make BCM2835 pin config fully generic.

   - Lots of Renesas SH-PFC incremental improvements"
