[PATCH V5 4/6] arm64: dts: qcom: sc7280: Add EUD dt node and dwc3 connector

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

 



Add the Embedded USB Debugger(EUD) device tree node. The
node contains EUD base register region and EUD mode
manager register regions along with the interrupt entry.
Also add the typec connector node for EUD which is attached to
EUD node via port. EUD is also attached to DWC3 node via port.
Also add the role-switch property to dwc3 node.
