Subject: [PATCH 0/4] iommu: Remove iommu_fwspec ops

Hi All,

Building on top of the arch_setup_dma_ops() cleanup[1], the next step
down the chain is {acpi,of}_dma_configure()... There's plenty to do
here, but it may as well start with this fairly self-contained little
cleanup, pruning yet more redundancy and exposed API surface.

Thanks,
Robin.
