From 3e35057ab8b11c232a7c0edeea3299d53c6d600d Mon Sep 17 00:00:00 2001

Subject: [PATCH 12/14] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB
property
The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.
