But the DWC3 USB controller can be connected to multiple ports and each port can have their own PHYs. Each port of the multiport controller can either be HS+SS capable or HS only capable Proper quantification of them is required to modify GUSB2PHYCFG and GUSB3PIPECTL registers appropriately. Add support for detecting, obtaining and configuring phy's supported by a multiport controller and limit the max number of ports supported to 4.
