Merge tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC mvebu platform changes from Olof Johansson: "This series contains changes for the Marvell EBU platforms (mvebu, orion, kirkwood, dove) that were not part of the first set of pull requests because of dependencies on the MMC tree, and being submitted a little late. Notable changes are: - More devices get moved out of board files into device tree descriptions. The remaining devices listed in there have patches that will get sent for 3.10, after which we can remove a lot of the board files entirely. We are doing the pinctrl and mmc drivers here, ethernet and PCI still remain. - SMP support for mvebu is improved with support for the local interrupt controller. - The Guruplug board file gets replaced with a DT description. Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches. To work around the merge conflicts, this branch rebases all patches on top of the respective MMC patches that did get merged into 3.9. The patches are all identical to the versions that were part of linux-next, but have a new commit date." * tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (90 commits) arm: mvebu: enable the SD card slot on Armada 370 Reference Design board ARM: kirkwood: topkick: init mvsdio via DT ARM: kirkwood: nsa310: convert to pinctrl ARM: Kirkwood: topkick: Enable i2c bus.
