[OpenWrt-Devel] [PATCH 2/3 v3] ARM: dts: Att Vitesse G5e switch to the Gemini SQ201

[Linus Walleij]

This adds the Vitesse G5e ethernet switch to the Square
One Itian SQ201 router device tree.

Signed-off-by: Linus Walleij <linus.walleij at linaro.org>
---
ChangeLog v2->v3:
- Use a fixed link for the ethernet port to the Vitesse
  DSA router chip.
ChangeLog v1->v2:
- Drop unrelated roofs mount point change.
