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

The IIF (ISP InterFace) is specialized BRU version 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.
