Hi folks, while working on some recent problesm with dwc3 and high-speed, high-bandwidth periodic endpoints, we found this old problem with usb_endpoint_maxp() where it returns wMaxPacketSize completely, not only the lowest 11 bits. This series tries to solve that by introducing a new usb_endpoint_maxp_mult() helper which returns ((wMaxPacketSize[12:11] >> 11) + 1) and fixes usb_endpoint_maxp() to return only wMaxPacketSize[10:0]. While at that, we're also fixing dwc3 to set a TRB's PCM1 to the value of usb_endpoint_maxp_mult() - 1. I'm yet to fully test these latest changes (hence RFC), however allmodconfig builds fine on x86.
