Merge branch 'pci/iova-dma-ranges'
- Add list of legal DMA address ranges to PCI host bridge (Srinath
Mannam)
- Reserve inaccessible DMA ranges so IOMMU doesn't allocate them (Srinath
Mannam)
- Parse iProc DT dma-ranges to learn what PCI devices can reach via DMA
(Srinath Mannam)
* pci/iova-dma-ranges:
PCI: iproc: Add sorted dma ranges resource entries to host bridge
iommu/dma: Reserve IOVA for PCIe inaccessible DMA address
PCI: Add dma_ranges window list
