The IIF (ISP InterFace) is a VSP2 function that reads data from external memory using two RPF instances and feed it to the ISP. The IIF support is modeled in the vsp1 driver as a new, simple, entity type. IIF is part of VSPX, a version of the VSP2 IP specialized for ISP interfacing. To prepare to support VSPX, support IIF first by introducing a new entity and by adjusting the RPF/WPF drivers to operate correctly when an IIF is present.
