From c31c83c970165b9f2cb4c0ad6ae89d0a8242cf7b Mon Sep 17 00:00:00 2001 From: Biju Das Date: Thu, 24 Aug 2017 10:35:44 +0100 Subject: [PATCH] PCI: rcar: Add device tree support for r8a7743/5 Add internal PCI bridge support for r8a7743/5 SoC. 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.
