If there is a DT node available for the root bridge's parent device,
use the dma configuration from that device node. For example, keystone
PCI devices would require dma_pfn_offset to be set correctly in the
device structure of the pci device in order to have the correct dma mask.
The DT node will

Also arm_iommu_create_mapping() has size parameter of size_t and
arm_setup_iommu_dma_ops() can take a value higher than that. So
limit the size to SIZE_MAX.

This driver translates the 32-bit AHB address from the dma master to

A still unconfirmed hardware bug prevents the IPMMU microTLB 0 to be
