The USB controller has next features: - Dual Role Device (DRD) controller - DWC3 compatible - Supports USB 2.0 host and USB 2.0 device interfaces - Supports full-speed (12 Mbps) and high-speed (480 Mbps) modes with USB device 2.0 interface - Supports on-chip USB PHY transceiver - Supports up to 16 bi-directional endpoints (that includes control endpoint 0) - Complies with xHCI 1.00 specification Only USB 2.0 is supported in Exynos850, so only UTMI+ PHY interface is specified in "phys" property (index 0) and PIPE3 is omitted (index 1).
