Author: ian Date: Sun Feb 12 00:52:22 2017 New Revision: 313674 URL: https://svnweb.freebsd.org/changeset/base/313674 Log: Enable usb low and full speed devices connected to the imx6 root hubs. This enables the PHY circuitry for UTMI+ level 2 and 3, and sets the flag to tell the ehci code that the root hub has a transaction translator in it. For imx6 we can use the standard ehci_get_port_speed_portsc() function to find out what speed device is connected to the port.
