[RFC 0/5] OMAP groundwork for IOMMU-based DMA API

[Ohad Ben-Cohen]

Another step towards generic IOMMU support on OMAP: eliminating
the public omap-specific find_iommu_device API.

Instead, we now bind iommu clients with their respective iommu device
using a private iommu member which is added to ARM's dev_archdata.

With this in hand, generic IOMMU API users will now work on OMAP without
utilizing any omap-specific API.

The changes are tested on OMAP3 (with omap3isp) and OMAP4 (with
remoteproc/rpmsg).

This is still RFC (2nd patch is probably the least elegant).

Ohad Ben-Cohen (5):
  ARM: dev_archdata: add private iommu extension
  ARM: OMAP: omap_device: add a method to set iommu private archdata
  ARM: OMAP: iommu: declare a private iommu binding struct
  ARM: OMAP3: bind omap3isp_device to its iommu device
  iommu/omap: eliminate the public omap_find_iommu_device() method
