Subject: [PATCH 6/9] 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.
