You may want to add "reg-names" to use named regions, as there is more than one region.

I've already told Ben he can't claim EHCI/OHCI register ranges at the bridge node, so there should be only one "reg" specifier.

Add initial documentation for the pci-rcar-gen2 driver device tree bindings. This is not yet complete and needs work on the sub-nodes for the PCI bus.
