Subject: [PATCH] iommu/ipmmu-vmsa: Include SoC part number in DT binding docs
Date: Mon, 19 Oct 2015 12:10:03 +0900 [thread overview]
Message-ID: <20151019031003.7878.28510.sendpatchset@little-apple> (raw)
From: Magnus Damm <damm+renesas@opensource.se>
Add part numbers for APE6 and current set of R-Car Gen2 SoCs to the
IPMMU DT binding documentation. The example is also updated to show
how the generic compatible string may be used as fallback.
