Varun Sethi bb5547acfc 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).

Hideki EIRAKU c2c460f7c1 iommu/shmobile: Add iommu driver for Renesas IPMMU modules
This is the Renesas IPMMU driver and IOMMU API implementation.

The IPMMU module supports the MMU function and the PMB function.  The
MMU function provides address translation by pagetable compatible with
ARMv6.  The PMB function provides address translation including
tile-linear translation.  This patch implements the MMU function.

The iommu driver does not register a platform driver directly because:
- the register space of the MMU function and the PMB function
  have a common register (used for settings flush), so they should ideally
  have a way to appropriately share this register.
- the MMU function uses the IOMMU API while the PMB function does not.
- the two functions may be used independently.
