From a37b3eafe8e9cbe7c7754bc6003c125b23749554 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Thu, 3 Dec 2015 07:51:39 +0900 Subject: PCI: rcar: Add gen2 fallback compatibility string for pcie-rcar Add fallback compatibility string for R-Car Gen 2 family. This is in keeping with the fallback scheme being adopted wherever appropriate for drivers for Renesas SoCs.
