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.
