Subject: [PATCH v7 0/5] media: renesas: vsp1: Add support for VSPX and IIF

The VSPX is a VSP2 function that reads data from
external memory using two RPF instances and feed it to the ISP.

The VSPX includes an IIF unit (ISP InterFace) 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.
