Subject: [PATCH/RFC 02/03] iommu/ipmmu-vmsa: Detect r8a77965 compat strings
Date: Wed, 20 Dec 2017 21:24:04 +0900 [thread overview]
Message-ID: <151377264404.17613.15104906014272414275.sendpatchset@little-apple> (raw)
In-Reply-To: <151377262568.17613.8610167192375932687.sendpatchset@little-apple>
From: Magnus Damm <damm+renesas@opensource.se>
Match on the r8a77965 SoC in the IPMMU driver. Software wise the same
IPMMU driver can be used as for other R-Car Gen3 SoCs, however the
hardware contains certain changes so using separate SoC compat strings
will allow us more fine grained control of features in the future.
