Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> --- - The dt-binding for usb-xhci has already been merged into linux-next: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/Documentation/devicetree/bindings/usb/usb-xhci.txt?h=next-20180717&id=4eb44f69e77141992e305d9e75e021b196071cdd - However, peripheral side is not yet (because the spec is not the same with other SoCs a little, so I need to modify the driver).
