From: Biju Das Date: Fri, 6 Oct 2017 17:15:17 +0000 (+0100) Subject: dmaengine: usb-dmac: Add compatible string for r8a7743/5 X-Git-Tag: v4.15-rc1~122^2~7^2~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5543de66e26776c20ecfb9e498c2561d74823ec3;p=thirdparty%2Fkernel%2Flinux.git dmaengine: usb-dmac: Add compatible string for r8a7743/5 This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbdmac engine is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,r8a7743-usb-dmac". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.
