[PATCH 0/2][SRU Xenial]

[AceLan Kao]

BugLink: http://bugs.launchpad.net/bugs/1632527

Impact:
The pinctrl-sunrisepoint/pinctrl-intel driver restores all pins
after resumed, but some pins are claimed/controlled by BIOS,
so it leads to the loss of functionality of the touchscreen
after S3 on Dell XPS 9350/9360.

Fix:
The patch makes the driver to restore the pins own by the driver, so
it makes the touchscreen continue working after S3.

Tested:
Tested on Dell XPS 13 9360

  gpio/pinctrl: sunxi: stop poking around in private vars

  pinctrl: intel: Only restore pins that are used by the driver
