Exynos IOMMU driver implements fault handling for SysMMU v1..v5. But the
abstraction currently used is not suited for SysMMU v7, as it has quite
different fault related register set.

This patch series reworks the mentioned fault handling abstraction and
adds fault handling support for SysMMU v7.

Hi Marek,

Can you please review and test this series? I only have my E850 (which
has VM-capable SysMMU register layout). So it would be nice to check
if it works fine with non-VM SysMMU v7 and older versions.

Thanks!

Applied, thanks.
