Subject: [PATCH 4/6] iommu/fsl: Add window permission flags for iommu_domain_window_enable API.
Date: Mon, 18 Feb 2013 18:22:17 +0530 [thread overview]
Message-ID: <1361191939-21260-5-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1361191939-21260-1-git-send-email-Varun.Sethi@freescale.com>
Each iommu window can have access permissions associated with it. Extended the
window_enable API to incorporate window access permissions.
