Merge tag 'ux500-gpio-pins-for-3.5' of... 

Merge tag 'ux500-gpio-pins-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/pinctrl

ux500 GPIO and pinctrl changes for kernel 3.5

* tag 'ux500-gpio-pins-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: ux500: switch MSP to using pinctrl for pins
  ARM: ux500: alter MSP registration to return a device pointer
  ARM: ux500: switch to using pinctrl for uart0
  ARM: ux500: delete custom pin control system
  ARM: ux500: switch over to Nomadik pinctrl driver
  pinctrl: add sleep state definition
  pinctrl/nomadik: implement pin configuration
  pinctrl/nomadik: implement pin multiplexing
  pinctrl/nomadik: reuse GPIO debug function for pins
  pinctrl/nomadik: break out single GPIO debug function
  pinctrl/nomadik: basic Nomadik pinctrl interface
  pinctrl/nomadik: !CONFIG_OF build error
  gpio: move the Nomadik GPIO driver to pinctrl

Context conflicts resolved in drivers/pinctrl/Kconfig and
drivers/pinctrl/Makefile.
