Subject: [PATCH 1/5] iommu/omap: Move data structures to omap-iommu.h
Date: Fri, 31 Mar 2017 14:10:44 +0200	[thread overview]
Message-ID: <1490962248-12602-2-git-send-email-joro@8bytes.org> (raw)
In-Reply-To: <1490962248-12602-1-git-send-email-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

The internal data-structures are scattered over various
header and C files. Consolidate them in omap-iommu.h.
