[PATCH v2] Added support for pogoplug e02 (pink/gray)

From: Christoph Junghans <hidden>
Date: 2015-01-13 01:22:12
Also in: linux-devicetree
Subsystem: arm and arm64 soc sub-architectures (common parts), open firmware and flattened device tree bindings, the rest · Maintainers: Arnd Bergmann, Krzysztof Kozlowski, Alexandre Belloni, Linus Walleij, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Possibly related (same subject, not in this thread)

The pogoplug differs from the SheevaPlug only by a
few details, but especially in the led assignments.
This patch was tested under Gentoo Linux and is
based on dts files from Arch Linux ARM and OpenWrt.
