Subject: [PATCH 1/4 v2] iommu/fsl: Store iommu domain information pointer in archdata.
Date: Tue, 20 Nov 2012 19:24:54 +0530 [thread overview]
Message-ID: <1353419697-31269-2-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1353419697-31269-1-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.
