This patch series aims to add USB3.1 HOST, Peri and DRD support on RZ/V2M EVK platform. The reset for both host and peri are located in USB3DRD block. The USB3DRD registers are mapped in the AXI address space of the Peripheral module. RZ/V2M is similar to R-Car XHCI but it doesn't require any firmware.
