Merge tag 'dt-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates (part 2) from Arnd Bergmann: "These are mostly new device tree bindings for existing drivers, as well as changes to the device tree source files to add support for those devices, and a couple of new boards, most notably Samsung's Exynos5 based Chromebook. The changes depend on earlier platform specific updates and touch the usual platforms: omap, exynos, tegra, mxs, mvebu and davinci." * tag 'dt-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: exynos: dts: cros5250: add EC device ARM: dts: Add sbs-battery for exynos5250-snow ARM: dts: Add i2c-arbitrator bus for exynos5250-snow ARM: dts: add mshc controller node for Exynos4x12 SoCs ARM: dts: Add chip-id controller node on Exynos4/5 SoC ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree ARM: davinci: da850-evm: add SPI flash support ARM: davinci: da850: override SPI DT node device name ARM: davinci: da850: add SPI1 DT node spi/davinci: add DT binding documentation spi/davinci: no wildcards in DT compatible property ARM: dts: mvebu: Convert mvebu device tree files to 64 bits ARM: dts: mvebu: introduce internal-regs node ARM: dts: mvebu: Convert all the mvebu files to use the range property ARM: dts: mvebu: move all peripherals inside soc ARM: dts: mvebu: fix cpus section indentation ARM: davinci: da850: add EHRPWM & ECAP DT node ARM/dts: OMAP3: fix pinctrl-single configuration ARM: dts: Add OMAP3430 SDP NOR flash memory binding ARM: dts: Add NOR flash bindings for OMAP2420 H4 ...
