2 master(s).
29 IOMMUs can be single-master or multiple-master. Single-master IOMMU devices
30 typically have a fixed association to the master device, whereas multiple-
31 master IOMMU devices can translate accesses from more than one master.

52 - #iommu-cells = <1>: Multiple master IOMMU devices may need to be configured
53   in order to enable translation for a given master. In such cases the single
