Subject: [PATCH V2 0/5] iommu/msm: Add DT adaptation and generic bindings support
Date: Wed, 6 Apr 2016 19:59:30 +0530 [thread overview]
Message-ID: <1459952975-1250-1-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@gmail.com>. This series folds the changes
in to the existing driver with the addition of generic bindings.

This series is based on the IOMMU probe deferral series from
Laurent Pinchart <laurent.pinchart@ideasonboard.com>.
https://lkml.org/lkml/2015/5/14/786
Tested this series on ifc6410 board.
[V2] Adapted the driver to use generic ARMV7S short descriptor pagetable ops
and addressed comments.
