Merge tag 'gemini-multiplat-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/soc

This patchset:

- Converts the Gemini platform to device tree.
- Deletes all the board files.
- Fixes the prerequisities for a multiplatform boot and
  switches to multiplatform.

* tag 'gemini-multiplat-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
  ARM: gemini: convert to ARMv4 multiplatform
  ARM: gemini: select ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR
  ARM: gemini: switch to sparse IRQs
  ARM: gemini: delete all boardfiles
  ARM: gemini: DT for the Cortina Gemini SoC platforms
  ARM: gemini: convert to MULTI_IRQ_HANDLER
