The USB3_PHY PLL controller and USB3_PHY DPLL clock generator share a common hardware nonretention reset, L3INIT_RST, which comes from the device power and reset manager. Upon DPLL_USB_OTG_SS hardware reset completion, the DPLLCTRL_USB_OTG_SS.PLL_STATUS[0] PLLCTRL_RESET_DONE bit is automatically updated to 1. For more information on the hardware reset source, see Reset Domains in Power, Reset, and Clock Management.
The DPLLCTRL_USB_OTG_SS itself has no software reset capabilities.
DPLLCTRL_USB_OTG_SS performs a software reset sequence on the DPLL_USB_OTG_SS in hardware (through the TINITZ signal activation).
