Merge tag 'pinctrl-for-v3.8-late' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull late pinctrl fixes from Linus Walleij: "Two patches appeared as of late, one was completely news to me, the other one was rotated in -next for the next merge window but turned out to be a showstopper. - Exynos Kconfig fixup - SIRF DT translation bug" * tag 'pinctrl-for-v3.8-late' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: sirf: replace of_gpio_simple_xlate by sirf specific of_xlate pinctrl: exynos: change PINCTRL_EXYNOS option
