Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree conversions and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms. Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases." Fix up conflicts as per Olof. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (185 commits) ARM: ux500: Rename dbx500 cpufreq code to be more generic ARM: dts: add missing ux500 device trees ARM: ux500: Stop registering the PCM driver from platform code ARM: ux500: Move board specific GPIO info out to subordinate DTS files ARM: ux500: Disable the MMCI gpio-regulator by default ARM: Kirkwood: remove kirkwood_ehci_init() from new boards ARM: Kirkwood: Add support LED of OpenBlocks A6 ARM: Kirkwood: Convert to EHCI via DT for OpenBlocks A6 ARM: kirkwood: Add NAND partiton map for OpenBlocks A6 ARM: kirkwood: Add support second I2C bus and RTC on OpenBlocks A6 ARM: kirkwood: Add support DT of second I2C bus ARM: kirkwood: Convert mplcec4 board to pinctrl ARM: Kirkwood: Convert km_kirkwood to pinctrl ARM: Kirkwood: support 98DX412x kirkwoods with pinctrl ARM: Kirkwood: Convert IX2-200 to pinctrl.
