From 89ae54baabdb31e9ee3b4d2b20e17fcdca08a1b2 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 17 Nov 2015 12:53:20 +0900 Subject: [PATCH] iommu/ipmmu-vmsa: Include SoC part number in DT binding docs 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.
