Hi all,
It seems omap-iommu hasn't had enough mainline users to avoid bitrotting
through the more recent evolution of the IOMMU API internals. These
patches attempt to bring it and its consumers sufficiently up-to-date
to work again, in a manner that's hopefully backportable. This is
largely all written by inspection, but I have managed to lightly boot
test patch #3 on an OMAP4 Pandaboard to confirm iommu_probe_device()
working again.
This supersedes my previous patch[1]. Patches #1 and #2 are functionally
independent, and can be applied directly to their respective trees if
preferred.
Thanks,
Robin.

Tested this series on omap4 w.r.t. remoteproc subsystem on v6.12-rc5, it
works fine; attached logs[2]. Therefore, for series please use:

Many thanks for working on the fix.
