<div class='commit-subject'>Merge tag 'pinctrl-v4.10-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl</div><div class='commit-msg'>Pull pin control fixes from Linus Walleij:
 "Another week, another set of pin control fixes. The subsystem has seen
  high patch-spot activity recently.

  The majority of the patches are for Intel, I vaguely think it mostly
  concern phones, tablets and maybe chromebooks and even laptops with
  this Intel Atom family chips.

  Driver fixes only:

   - one fix to the Berlin driver making the SD card work fully again.

   - one fix to the Allwinner/sunxi bias function: one premature change
     needs to be partially reverted.

   - the remaining four patches are to Intel embedded SoCs: baytrail
     (three patches) and merrifield (one patch): register access
     debounce fixes and a missing spinlock"

* tag 'pinctrl-v4.10-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl: baytrail: Add missing spinlock usage in byt_gpio_irq_handler
  pinctrl: baytrail: Debounce register is one per community
  pinctrl: baytrail: Rectify debounce support (part 2)
  pinctrl: intel: merrifield: Add missed check in mrfld_config_set()
  pinctrl: sunxi: Don't enforce bias disable (for now)
  pinctrl: berlin-bg4ct: fix the value for "sd1a" of pin SCRD0_CRD_PRES
