Message

As exynos-iommu driver is not a critical platform driver, it can be
converted to loadable module, to avoid loading it on non-Exynos
platforms in order to improve the RAM footprint. This patch series
converts it to a module and does some related cleanups. IOMMU/DMA
specifics were taken into the account, so remove/exit methods weren't
added.

Sam Protsenko (4):
  iommu: Export iommu_group_default_domain() API
  iommu/exynos: Fix retval on getting clocks in probe
  iommu/exynos: Modularize the driver
  iommu/exynos: Rearrange the platform driver code
