Subject: [PATCH V3 0/7] iommu/msm: Add DT adaptation and generic bindings support
Date: Mon, 2 May 2016 00:24:28 +0530 [thread overview]
Message-ID: <1462128875-20988-1-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
Tested this series on ifc6410 board.
[V3] Addressed comments to correct the usage
of the #iommu-cells binding, improve the flush_iotlb_range function,
added a new patch to use writel_relaxed for register access and split
up the documentation patch.
[V2] Adapted the driver to use generic ARMV7S short descriptor pagetable ops
and addressed comments.
