[PATCH 0/8] Enable EUD on Qualcomm sm8450 SoC

[Elson Roy Serrao]

The Embedded USB Debugger (EUD) is a mini High-Speed USB on-chip hub to
support the USB-based debug and trace capabilities on Qualcomm devices.
The current implementation lacks in below aspects that are needed for
proper EUD functionality.

1.) HS-Phy control: EUD being a HS hub needs HS-Phy support for it's
    operation. Hence EUD module should enable/disable HS-phy
    accordingly.
	
2.) Proper routing of USB role switch notifications: EUD hub is physically
    present in between the USB connector and the USB controller. So the
    usb role switch notifications originating from the connector should
    route through EUD. EUD also relies on role switch notifications to
    communicate with the USB, regarding EUD attach/detach events.

This series aims at implementing the above aspects to enable EUD on
Qualcomm sm8450 SoC.
