Merge tag 'pinctrl-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.8 kernel cycle.

  Nothing stands out as especially exiting: new drivers, new subdrivers,
  lots of cleanups and incremental features.

  Business as usual.

  New drivers:

   - New driver for Oxnas pin control and GPIO.  This ARM-based chipset
     is used in a few storage (NAS) type devices.

   - New driver for the MAX77620/MAX20024 pin controller portions.

   - New driver for the Intel Merrifield pin controller.

  New subdrivers:

   - New subdriver for the Qualcomm MDM9615

   - New subdriver for the STM32F746 MCU

   - New subdriver for the Broadcom NSP SoC.

  Cleanups:

   - Demodularization of bool compiled-in drivers.

  Apart from this there is just regular incremental improvements to a
  lot of drivers, especially Uniphier and PFC"
