Two of them are fully functional in host, device and OTG mode including USB2 support. They are connected to dedicated PHYs, that also support USB-C's DisplayPort alternate mode. The third controller is connected to one of the combphy's shared with PCIe and SATA. It can only be used in host mode and does not support USB2. Compared to the other controllers this one needs some extra clocks.
