Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson: "Ladies and gentlemen, we proudly announce to you the latest branch of ARM device tree contents for the mainline kernel. Come and see, come and see! No less than twentythree thousand lines of additions! Just imagine the joy you will have of using your mainline kernel on newly supported hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or UniPhier hardware! For those of you feeling less adventurous, added hardware support on platforms such as TI DM814x and Gumstix Overo platforms might be more of your liking. We've got something for everyone here! Ahem. Cough. So, anyway... This is the usual large batch of DT updates. Lots and lots of smaller changes, some of the larger ones to point out are: - Rockchip veyron (Chromebook) support, as well as several other new boards - DRM support on Atmel AT91SAM9N12EK - USB additions on some Allwinner platforms - Mediatek MT6580 support - Freescale i.MX6UL support - cleanups for Renesas shmobile platforms - lots of added devices on LPC18xx - lots of added devices and boards on UniPhier There's also some dependent code added here, in particular some branches that are primarily merged through the clock tree" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (389 commits) ARM: tegra: Add gpio-ranges property ARM: tegra: Fix AHB base address on Tegra20, Tegra30 and Tegra114 ARM: tegra: Add Tegra124 PMU support ARM: tegra: jetson-tk1: Add GK20A GPU DT node ARM: tegra: venice2: Add GK20A GPU DT node ARM: tegra: Add IOMMU node to GK20A ARM: tegra: Add CPU regulator to the Jetson TK1 device tree ARM: tegra: Add entries for cpufreq on Tegra124 ARM: tegra: Enable the DFLL on the Jetson TK1 ARM: tegra: Add the DFLL to Tegra124 device tree ARM: dts: zynq: Add devicetree entry for Xilinx Zynq reset controller.
