[PATCH V0 0/2] DT changes for Embedded USB Debugger(EUD)

[Souradeep Chowdhury]

This patch contains the DT changes for EUD from the QCOM tree.
The DT changes have been reverted from USB tree to avoid
conflicts. The DT changes for EUD should go through the QCOM
tree.

  arm64: dts: qcom: sc7280: Add EUD dt node and dwc3 connector
  arm64: dts: qcom: sc7280: Set the default dr_mode for usb2

[PATCH V0 1/2] arm64: dts: qcom: sc7280: Add EUD dt node and dwc3 connector

[Souradeep Chowdhury]

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.
