4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Martin Blumenstingl <[email protected]> [ Upstream commit b83687f359d9b4128073f06ab7a06489eb04aa7c ] The LibreTech CC ("Le Potato") board provides four USB connectors. These are provided by a hub which is connected to the SoC's USB controller. Enable the SoC's USB controller to make the USB ports usable. Also turn on the HDMI_5V regulator when powering on the PHY because (even though it's not shown in the schematics) HDMI_5V also supplies the USB VBUS.
