     13  A Rockchip DRM iommu translates io virtual addresses to physical addresses for
     14  its master device. Each slave device is bound to a single master device and
     15  shares its clocks, power domain and irq.
     16
     17  For information on assigning IOMMU controller to its peripheral devices,
     18  see generic IOMMU bindings.
