[PATCH 14/22] ARM: dts: add a devicetree for Raidsonic NAS IB-4220-B

[Linus Walleij]

This devicetree is simply based on the board file in
arch/arm/mach-gemini/board-nas4220b.c and contain the
equivalent platform data, mainly just moving the GPIOs
from the global numberspace to explicitly reference &gpio1.

Thanks Hans! I folded this into the NAS 4220 device tree
and added your Signed-off-by to the patch.

You can remove the PCI entries I've seen on your git tree.
NAS 4220 has no PCI interface

OK! I just assumed it was on that machine since you were
commenting on the driver, I cut it now.
