This series adds the dt-binding and driver support for SM6115 / SM4250
EUD (Embedded USB Debugger) block available on Qualcomm SoCs.

The EUD is a mini-USB hub implemented on chip to support the USB-based debug
and trace capabilities.

EUD driver listens to events like USB attach or detach and then
informs the USB about these events via ROLE-SWITCH.
