+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.
