Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board updates from Olof Johansson: "This branch contains a set of various board updates for ARM platforms. A few shmobile platforms that are stale have been removed, some defconfig updates for various boards selecting new features such as pinctrl subsystem support, and various updates enabling peripherals, etc." Fix up conflicts mostly as per Olof. * tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (58 commits) ARM: S3C64XX: Add dummy supplies for Glenfarclas LDOs ARM: S3C64XX: Add registration of WM2200 Bells device on Cragganmore ARM: kirkwood: Add Plat'Home OpenBlocks A6 support ARM: Dove: update defconfig ARM: Kirkwood: update defconfig for new boards arm: orion5x: add DT related options in defconfig arm: orion5x: convert 'LaCie Ethernet Disk mini v2' to Device Tree arm: orion5x: basic Device Tree support arm: orion5x: mechanical defconfig update ARM: kirkwood: Add support for the MPL CEC4 arm: kirkwood: add support for ZyXEL NSA310 ARM: Kirkwood: new board USI Topkick ARM: kirkwood: use gpio-fan DT binding on lsxl ARM: Kirkwood: add Netspace boards to defconfig ARM: kirkwood: DT board setup for Network Space Mini v2 ARM: kirkwood: DT board setup for Network Space Lite v2 ARM: kirkwood: DT board setup for Network Space v2 and parents leds: leds-ns2: add device tree binding ARM: Kirkwood: Enable the second I2C bus ARM: mmp: select pinctrl driver ...
