[PATCH v2 0/6] media: renesas: vsp1: Add support for IIF

[Jacopo Mondi]

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.
