Subject: [PATCH 1/5 v11] iommu/fsl: Make iova dma_addr_t in the iommu_iova_to_phys API.
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@...escale.com>
---
changes in v11:
- Made iova dma_addr_t instead of u64.
- no change in v10.
