Merge tag 'versatile-dt-cleanup-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/dt
Versatile DT cleanups from Linus Walleij: "this is a first pull request for my cleanups for the Versatile, as the finished stuff should not be sitting in my tree but in ARM SoC. This completes the ARM RealView PB1176 and PB11MPCore device trees, and moves the Versatile to use power/reset. The idea is to keep working on this cleanup branch and send additional patches on top of this one as the prerequisites are merged into the MTD and FBDEV subsystems. So please create a special versatile cleanup branch (or suggest another approach). As it happens, board files and device trees need to change at the same time to make logical sense, especially for Versatile where auxdata is replaced with DT entries, such as when reset is moved in the last patch in this set. The MTD and CLCD changes will share this characteristic." Versatile family cleanups step 1: - Finalize RealView the PB1176 and PB11MPCore device trees - Move Versatile to use the power/reset driver instead of a custom restart hook * tag 'versatile-dt-cleanup-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator: ARM: versatile: move restart to the device tree ARM: realview: add the DS1338 RTC to PB1176 DT ARM: pb1176: add ethernet to devicetree ARM: pb1176: add ISP1761 USB OTG host controller ARM: pb1176: add AACI to the device tree ARM: pb1176: add ICST307 clocks to the device tree ARM: realview: fix up PB11MP flash compat strings ARM: realview: add flash devices to the PB1176 DTS Signed-off-by: Olof Johansson <olof@lixom.net>
