Merge tag 'soc-arm-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC ARM code updates from Arnd Bergmann:
 "These are again very minimal updates:

   - A workaround for firmware on Google Nexus 10

   - A fix for early debugging on OMAP1

   - A rework for Microchip SoC configuration

   - Cleanups on OMAP2 an R-Car-Gen2"

* tag 'soc-arm-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
  ARM: omap2: dead code cleanup in kconfig for ARCH_OMAP4
  ARM: OMAP1: Fix DEBUG_LL and earlyprintk on OMAP16XX
  arm64: Kconfig: provide a top-level switch for Microchip platforms
  ARM: shmobile: rcar-gen2: Use of_phandle_args_equal() helper
  ARM: omap: fix all kernel-doc warnings
  ARM: omap2: Replace scnprintf with strscpy in omap3_cpuinfo
  ARM: samsung: exynos5250: Allow CPU1 to boot
