[OpenWrt-Devel] [PATCH 5/5 v3] ARM: dts: Add the FOTG210 USB host to Gemini

[Linus Walleij]

This adds the FOTG210 USB host controller to the Gemini
device trees. In the main SoC DTSI it is flagged as disabled
and then it is selectively enabled on the devices that utilize
it (these per-platform enablements are done on the out-of-tree
OpenWrt patch set). It is not enabled on the Itian SquareOne
NAS/router since this instead has a VIA host controller
soldered on the PCI port, and can gate off these USB host
controllers.

Signed-off-by: Linus Walleij <linus.walleij at linaro.org>

USB maintainers: I will merge this through the ARM SoC tree,
the patch is only included in the series for context.
