This feature relates to Anurag patch [1] and a thread [2] from earlier Where Anurags patch focus on setting U1/U2 latency in the BOS descriptor from the devicetree, this patch focuses on having a configfs interface for forcing the UDC (here the dwc3) to not enable U1/U2 and reject the SET_SEL(U1/U2). Looking forward to input. [1] https://www.spinics.net/lists/linux-usb/msg179732.html [2] https://www.spinics.net/lists/linux-usb/msg179393.html
