Author: loos Date: Tue Sep 27 16:06:01 2016 New Revision: 306368 URL: https://svnweb.freebsd.org/changeset/base/306368 Log: MFC r306050: If present, honor the USB port mode (host or peripheral) set on DTS, if not, keep the beaglebone defaults: USB0 -> peripheral/gadget, USB1 -> host. This is only a workaround as in fact fact this hardware is capable of detect the USB port mode based on type of cable and act according with the detected mode. Unfortunately the driver does not handle that at moment.
