[PATCH 0/5] pinctrl: cherryview: fixes and enhancements

["Dan O'Donovan" <dan@xxxxxxxxxx>]

This series includes a number of fixes and enhancements for the
Cherryview pinctrl/gpio driver, developed during integration on the
UP Board (based on the Intel X5-Z8350 "Cherry Trail" Atom SoC).

Of particular note is a workaround for a documented silicon bug which
causes data corruption of concurrent accesses to the GPIO controller
registers on this SoC.

Other patches include clean-up of checkpatch warnings, implementation
of additional pin config functions and options, and a fix for a loss
of pin config register state that can occur when switching in and out
of GPIO pin mode.

Dan O'Donovan (5):
  pinctrl: cherryview: convert bare unsigned to unsigned int
  pinctrl: cherryview: add option to set open-drain pin config
  pinctrl: cherryview: add handlers for pin_config_group_get/set
  pinctrl: cherryview: prevent concurrent access to GPIO controllers
  pinctrl: cherryview: restore padctrl1 reg when gpio is disabled
