iommu: Implement mapping IOMMUs for PCI devices Systems such as Apple's M1 and M2 SoCs may have separate IOMMUs for each PCIe root port. In this case the right IOMMU for a PCI device behind a particular root port is described by an "iommu-map" property in the device tree. Parse this property and use it to find the right IOMMU device for PCI devices. Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
