Subject: [RFC][PATCH 1/3] iommu/fsl: Store iommu domain information pointer in archdata.
Date: Wed, 19 Sep 2012 18:47:10 +0530 [thread overview]
Message-ID: <1348060632-12997-2-git-send-email-b16395@freescale.com> (raw)

From: Varun Sethi <Varun.Sethi@freescale.com>
Add a new field in the device (powerpc) archdata structure for storing iommu domain
information pointer. This pointer is stored when the device is attached to a particular
domain.
