The HiKey960 has a fairly complex USB configuration due to it needing to support a USB-C port for host/device mode and multiple USB-A ports in host mode, all using a single USB controller. See schematics here: https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf This driver acts as a usb-role-switch intermediary, intercepting the role switch notifications from the tcpm code, and passing them on to the dwc3 core. In doing so, it also controls the onboard hub and power gpios in order to properly route the data lines between the USB-C port and the onboard hub to the USB-A ports.
