Right? Actually regarding the bit I wrote above, it might be helpful to pass the PCI_DEVID() into both of_iommu_configure and of_dma_configure. While this may or may not be sufficient, I think there is no question about it being needed for the ARM SMMU with PCI, so we may as well add it at the point when you touch the same lines already. In the platform bus case, just pass zero here.
