Subject: [PATCH 2/5 v9] powerpc: Add iommu domain pointer to device archdata
Date: Thu, 14 Mar 2013 00:15:07 +0530 [thread overview]
Message-ID: <1363200310-11513-3-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1363200310-11513-1-git-send-email-Varun.Sethi-KZfg59tc24xl57MIdRCFDg@public.gmane.org>
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.
