Subject: [PATCH 1/5 v11] iommu/fsl: Make iova dma_addr_t in the iommu_iova_to_phys API.
Date: Fri, 29 Mar 2013 01:23:58 +0530	[thread overview]
Message-ID: <1364500442-20927-2-git-send-email-Varun.Sethi@freescale.com> (raw)
In-Reply-To: <1364500442-20927-1-git-send-email-Varun.Sethi@freescale.com>

This is required in case of PAMU, as it can support a window size of up
to 64G (even on 32bit). 

Signed-off-by: Varun Sethi <Varun.Sethi@freescale.com>
---
changes in v11:
- Made iova dma_addr_t instead of u64.
- no change in v10.
