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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJV5OMWAAoJEIwa5zzehBx3r2QP/1skn0zzgfvbK0kkPOh9q3Jk jX1elN4Wde1SnScz8UbdVb9nmdbhxsuYE/3+Lz7yCndWScBiak4qcsNHrSRhh3FA ST7Ub8DLc2TxY9K7eDkyVCcNkP35+UQTHCN76R5Lgrlfw3UO9Zr3xPFX3+Kd6aWz 9X8UnvJacQQIN/vO6J02kB96sKPEIANfuMgO6vDSbmcZ1RrdlHzjoRwAV0smECtJ NyOh+NQdPBR0gSl/peyKzAXoDHNXpDotltTmIz3tPA+dYBO/qG//B73H/oqox0ql AKAktyaDzdxXEuixPtAroo4dDy3xuIQ6xU+DNhPWQq0BgaxHWqkwq60d74ot8vCz 8gvC8pwA6gavbqVFNePOnwPNSyWZX01scX4fp903NjVM8/rGPvCR4y6p8lFIyVkG P0L8rmY/UYq3fieaAb1W0odASDrQpgg3zsHD7to43hz6jaRnMRCpA8nTVqJcyHqI E6YfGQH87Kpbvkjo0FYqo5P6xCCRTq+QUys6JruNYg05R/gd8AG7cXaVNO3yvg3T lRwNXDBt/zcp2exKnGR0IdGMUMICzsuoB8ZePkQdIWwePrd4AzT5qYJe/txmg1rd q+9VJqQkeF+txLd9XUV2W/Hcuzu3ZPCbs97I9tTKQHMGwKUZaPfuk2r4+4K+Ps5a dYwdms39p6AIT43rK+m3 =D2Pm -----END PGP SIGNATURE----- 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.
