Author: loos Date: Tue Sep 20 19:06:58 2016 New Revision: 306050 URL: https://svnweb.freebsd.org/changeset/base/306050 Log: 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.
