If anyone has any objections, please let me know. ------------------ From: Martin Blumenstingl [ Upstream commit 458baa95c86406c81c6ebac0a98d1689075a3ec4 ] The USB configuration on GXM is slightly different than on GXL. The dwc3 controller's internal hub has three USB2 ports (instead of 2 on GXL) along with a dedicated USB2 PHY for this port. However, it seems that there are no pins on GXM which would allow connecting the third port to a physical USB port. Passing the third PHY is required though, because without it none of the other USB ports is working (this seems to be a limitation of how the internal USB hub works, if one PHY is disabled then no USB port works).
