On SAMA5D2 SoCs, Port C of USB Host contains a High-Speed Inter-Chip (HSIC)
transceiver. It can be used for USB chip-to-chip interconnect with a 2-signal
(strobe, data) synchronous serial interface using 240 MHz DDR signaling.

External cables, connectors, and hot plug & play are not supported.

This patch series enables this feature.
