Subject: [PATCH 0/5] iommu/msm: Add DT adaptation and generic bindings support
Date: Wed, 12 Aug 2015 20:17:44 +0530	[thread overview]
Message-ID: <1439390869-6347-1-git-send-email-sricharan@codeaurora.org> (raw)

The msm_iommu.c driver currently works based on platform data. A single master
device can be connected to more than one iommu and multiple contexts in each
of the iommu. This association between master and iommus was represented
from platform data using parent/child devices. The master drivers were
responsible for attaching all of the iommus/context to a domain. Now the
platform data support is removed and DT support is added. The master/iommus
are added through generic iommu bindings.

This is essentially rework of the patch posted earlier by
Rob Clark <robdclark-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>. This series folds the changes
in to the existing driver with the addition of generic bindings.

        http://www.spinics.net/lists/linux-arm-msm/msg10077.html

This series is based on the IOMMU probe deferral series from
Laurent Pinchart <laurent.pinchart-ryLnwIuWjnjg/C1BVhZhaw@public.gmane.org>

        https://lkml.org/lkml/2015/5/14/786

Tested this series on ifc6410 board.
