Author: sgalabov Date: Thu Apr 7 11:20:03 2016 New Revision: 297670 URL: https://svnweb.freebsd.org/changeset/base/297670 Log: Initial import of Ralink/Mediatek MIPS SoC support #5 USB support This revision adds USB (EHCI/OHCI/OTG, depending on SoC type) support for various Ralink/Mediatek SoCs. Currently USB is not supported on MT7621, this will be a future addition. A USB PHY driver is also included, so that we can properly initialize the USB PHY (e.g., clocks, resets, registers where needed), before attempting to initialize EHCI/OHCI/OTG functionality.
