Optional properties:

access to the IOMMU configuration registers
+- qcom,iommu-bfb-regs : An array of unsigned 32-bit integers corresponding to
+ BFB register addresses that need to be configured for performance tuning
+ purposes. If this property is present, the qcom,iommu-bfb-data must also be

+ implementation-defined register region.
