Merge tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij: "Main pin control pull request for the v3.13 cycle. The changes hitting arch/blackfin are ACKed by the Blackfin maintainer, and the device tree bindings are ACKed to the extent possible by someone from the device tree maintainers group. - Blackfin ADI pin control driver, we move yet another architecture under this subsystem umbrella. - Incremental updates to the Renesas Super-H PFC pin control driver. New subdriver for the r8a7791 SoC. - Non-linear GPIO ranges from the gpiolib side of things, this enabled simplified device tree bindings by referring entire groups of pins on some pin controller to act as back-end for a certain GPIO-chip driver. - Add the Abilis TB10x pin control driver used on the ARC architecture. Also the corresponding GPIO driver is merged through this tree, so the ARC has full support for pins and GPIOs after this. - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller instances. The i.MX1 and i.MX27 is an entirely new family (silicon) of controllers whereas i.MX50 is a variant of the previous supported controller. - Then the usual slew of fixes, cleanups and incremental updates" The ARC DT changes are apparently still pending, that hopefully gets sorted out in a timely manner. * tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (48 commits) pinctrl: imx50: add pinctrl support code for the IMX50 SoC pinctrl: at91: copy define to driver pinctrl: remove minor dead code pinctrl: imx: fix using pin->input_val wrongly pinctrl: imx1: fix return value check in imx1_pinctrl_core_probe() gpio: tb10x: fix return value check in tb10x_gpio_probe() gpio: tb10x: use module_platform_driver to simplify the code pinctrl: imx27: imx27 pincontrol driver pinctrl: imx1 core driver pinctrl: sh-pfc: r8a7791 PFC support sh-pfc: r8a7778: Add CAN pin groups gpio: add TB10x GPIO driver pinctrl: at91: correct a few typos pinctrl: mvebu: remove redundant of_match_ptr pinctrl: tb10x: use module_platform_driver to simplify the code pinctrl: tb10x: fix the error handling in tb10x_pinctrl_probe() pinctrl: add documentation for pinctrl_get_group_pins() pinctrl: rockchip: emulate both edge triggered interrupts pinctrl: rockchip: add rk3188 specifics pinctrl: rockchip: remove redundant check ...
