Subject: [PATCH 1/6 v8] iommu/fsl: Store iommu domain information pointer in archdata.
Date: Mon, 18 Feb 2013 18:22:14 +0530 [thread overview]
Message-ID: <1361191939-21260-2-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1361191939-21260-1-git-send-email-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.
