From 0e98f9d5f0b4a9012bd4fb5ff88b3ea290deb6a8 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 27 Jan 2017 20:46:27 +0100 Subject: [PATCH] ravb: Support 1Gbps on R-Car H3 ES1.1+ and R-Car M3-W The limitation to 10/100Mbit speeds on R-Car Gen3 is valid for R-Car H3 ES1.0 only. Check for the exact SoC model to allow 1Gbps on newer revisions of R-Car H3, and on R-Car M3-W.
