Subject: [PATCH 0/2] iommu/exynos: Add fault handling on SysMMU v7

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.

Sam Protsenko (2):
  iommu/exynos: Abstract getting the fault info
  iommu/exynos: Implement fault handling on SysMMU v7
