Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc cleanups, part 2 from Olof Johansson: "A shorter cleanup branch submitted separately due to dependencies with some of the previous topics. Major thing here is that the Broadcom bcmring platform is removed. It's an SoC that's used on some stationary VoIP platforms, and is in desperate need of some cleanup. Broadcom came back and suggested that we just deprecate the platform for now, since they aren't going to spend the resources needed on cleaning it up, and there are no users of the platform directly from mainline." Fix some conflicts due to BCM2835 getting added next to the removed BCMRING, and removal of tegra files that had been converted to devicetree. * tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: Orion5x: ts78xx: Add IOMEM for virtual addresses. ARM: ux500: use __iomem pointers for MMIO ARM: Remove mach-bcmring ARM: clps711x: Remove board support for CEIVA ARM: clps711x: Fix register definitions ARM: clps711x: Fix lowlevel debug-macro ARM: clps711x: Added simple clock framework pinctrl: tegra: move pinconf-tegra.h content into drivers/pinctrl ARM: tegra: delete unused headers ARM: tegra: remove useless includes of <mach/*.h> ARM: tegra: remove dead code
