This series adds the dt-binding and driver support for SM6115 / SM4250 EUD (Embedded USB Debugger) block available on Qualcomm SoCs. It also enables the same for QRB4210-RB2 boards by default (the user still needs to enable the same via sysfs). 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.
