Subject: [PATCH 1/3 v11] powerpc: Add iommu domain pointer to device archdata
Date: Thu, 20 Jun 2013 21:31:29 +0530 [thread overview]
Message-ID: <1371744089-17780-3-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1371744089-17780-1-git-send-email-Varun.Sethi@freescale.com>
Add an iommu domain pointer to device (powerpc) archdata. Devices
are attached to iommu domains and this pointer provides a mechanism
to correlate between a device and the associated iommu domain. This
field is set when a device is attached to a domain.
