Subject: [PATCH v3 1/4] PCI: rcar-gen2: add gen2 fallback compatibility string
Date: Mon, 18 Jan 2016 14:09:42 +0900 [thread overview]
Message-ID: <1453093785-21067-2-git-send-email-horms+renesas@verge.net.au> (raw)
In-Reply-To: <1453093785-21067-1-git-send-email-horms+renesas@verge.net.au>
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.
