| * dt-bindings: PCI: rcar: Add device tree support for r8a7743Biju Das2018-03-061-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for r8a7743. The Renesas RZ/G1M(R8A7743)PCIe controller is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,pcie-rcar-gen2". Adding the SoC-specific compatible values here has three purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values. 3. Allow the driver to support SoC specific implementations in future as necessary.

Add a second register bank for the configuration memory area. The device tree specs do specify a memory range for configuration space but it is not applicable to custom accessors like this.

The Renesas RZ/G1[ME] (R8A7743/5) internal PCI bridge is identical to the R-Car Gen2 family. This doesn't change the driver, so it does nothing by itself. But it does mean that checkpatch won't complain about a future patch that adds "renesas,pci-r8a7743" to a DT, which helps ensure that shipped DTs use documented compatibility strings.
