Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board updates from Olof Johansson: "This branch is reducing in size for every release since most board-related changes have started happening in devicetrees now. Still, we have some things going on here. * Renesas platforms are still adding a bit more legacy device support, something that should trail off shortly as they move to full DT * We group most defconfig updates into this branch out of old habits * Removal of legacy OMAP2 platforms over to DT continues, and a handful of old code is being removed here" * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (94 commits) ARM: dts: OMAP2: fix interrupt number for rng ARM: dts: Split omap3 pinmux core device ARM: dts: Add omap specific pinctrl defines to use padconf addresses ARM: bcm2835: bcm2835_defconfig updates ARM: msm_defconfig: Enable restart driver defconfig: msm_defconfig: Enable CONFIG_ARCH_MSM8974 ARM: msm: Add support for APQ8074 Dragonboard ARM: exynos_defconfig: Enable S2MPS11 voltage regulator ARM: tegra: Enable DRM panel support ARM: shmobile: mackerel: Fix USBHS pinconf entry ARM: shmobile: Let Koelsch multiplatform boot with Koelsch DTB ARM: shmobile: Let Lager multiplatform boot with Lager DTB ARM: shmobile: Remove non-multiplatform Koelsch reference support ARM: shmobile: Remove non-multiplatform Lager reference support ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMT ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT ARM: shmobile: koelsch-reference: Remove duplicate CCF initialization ARM: shmobile: lager-reference: Enable multiplaform kernel support ARM: shmobile: armadillo: Set backlight enable GPIO ARM: shmobile: Koelsch: add Ether support ...
