[linux-sunxi] [PATCH 6/6] ARM: dts: sun9i: Enable USB support on A80 Optimus board

[Chen-Yu Tsai]

Signed-off-by: Chen-Yu Tsai <w...@csie.org>
---
This patch does not use sunxi-common-regulators.dtsi, but adds the
regulators directly. To use the common regulators file, we would
need to use phandles and switch to preprocessor includes to support
that.
