[PATCH 0/2] Reuse generic PCI DMA alias parsing code for the ARM SMMU

[Will Deacon <will.deacon-5wv7dgnIgG8@public.gmane.org>]

Hi all,

This series of two patches removes the (incomplete) PCI DMA alias parsing
code from the ARM SMMU driver and instead modifies the generic
iommu_group_get_for_pci_dev implementation to return the alias as well as
the group.

One snag is that iommu_group_get_for_pci_dev is no longer static after
the change, but returning the alias from iommu_group_get_for_dev doesn't
feel right either, as we don't currently have any generic IOMMU grouping
for the platform bus.

Feedback welcome,

Will
