[PATCH v3 0/2] add support for the R-Car H2 and M2 xHCI controllers

This patch set adds the USB xHCI support for the R-Car H2 and M2 SoCs.
These SoCs use an xHCI but still need specific initialization, mainly
to setup the firmware downloading and the specific registers.

This patch set is based on the usb-next branch of Greg usb.git tree.
