Subject: [PATCH v2] dt-bindings: PCI: rcar: Add device tree support for r8a7743
Date: Tue, 14 Nov 2017 09:59:03 +0000 [thread overview]
Message-ID: <1510653543-53770-1-git-send-email-biju.das@bp.renesas.com> (raw)
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.
