From bb9175051aedb33dcf44741c6f145107ab132a87 Mon Sep 17 00:00:00 2001 From: Varun Sethi Date: Mon, 15 Jul 2013 10:20:55 +0530 Subject: [PATCH] powerpc: Add iommu domain pointer to device archdata 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.
