[PATCH v4 6/6] ARM: dts: imx6qdl-udoo.dtsi: fix onboard USB HUB property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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.
