Merge tag 'pinctrl-v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij: "Here is the bulk of pin control changes for the v4.2 series: Quite a lot of new SoC subdrivers and two new main drivers this time, apart from that business as usual. Details: Core functionality: - Enable exclusive pin ownership: it is possible to flag a pin controller so that GPIO and other functions cannot use a single pin simultaneously. New drivers: - NXP LPC18xx System Control Unit pin controller - Imagination Pistachio SoC pin controller New subdrivers: - Freescale i.MX7d SoC - Intel Sunrisepoint-H PCH - Renesas PFC R8A7793 - Renesas PFC R8A7794 - Mediatek MT6397, MT8127 - SiRF Atlas 7 - Allwinner A33 - Qualcomm MSM8660 - Marvell Armada 395 - Rockchip RK3368 Cleanups: - A big cleanup of the Marvell MVEBU driver rectifying it to correspond to reality - Drop platform device probing from the SH PFC driver, we are now a DT only shop for SuperH - Drop obsolte multi-platform check for SH PFC - Various janitorial: constification, grammar etc Improvements: - The AT91 GPIO portions now supports the set_multiple() feature - Split out SPI pins on the Xilinx Zynq - Support DTs without specific function nodes in the i.MX driver" * tag 'pinctrl-v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits) pinctrl: rockchip: add support for the rk3368 pinctrl: rockchip: generalize perpin driver-strength setting pinctrl: sh-pfc: r8a7794: add SDHI pin groups pinctrl: sh-pfc: r8a7794: add MMCIF pin groups pinctrl: sh-pfc: add R8A7794 PFC support pinctrl: make pinctrl_register() return proper error code pinctrl: mvebu: armada-39x: add support for Armada 395 variant pinctrl: mvebu: armada-39x: add missing SATA functions pinctrl: mvebu: armada-39x: add missing PCIe functions pinctrl: mvebu: armada-38x: add ptp functions pinctrl: mvebu: armada-38x: add ua1 functions pinctrl: mvebu: armada-38x: add nand functions pinctrl: mvebu: armada-38x: add sata functions pinctrl: mvebu: armada-xp: add dram functions pinctrl: mvebu: armada-xp: add nand rb function pinctrl: mvebu: armada-xp: add spi1 function pinctrl: mvebu: armada-39x: normalize ref clock naming pinctrl: mvebu: armada-xp: rename spi to spi0 pinctrl: mvebu: armada-370: align spi1 clock pin naming pinctrl: mvebu: armada-370: align VDD cpu-pd pin naming with datasheet ...
