This patch adds the bindings for the R-Car PCIe driver. The driver resides under drivers/pci/host/pcie-rcar.cquoted

v6: - Correct DT bindings description for reg and clocksquoted
v5: - Add PCIe bus clock reference - Add additional interrupt bindings - Use dma-ranges property to specify inbound memory regionsPut these under --- tear line, please.quoted
