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
