2025-05-02	media: renesas: vsp1: rwpf: Support operations with IIF	Jacopo Mondi
	When the RPF/WPF units are used for ISP interfacing through the IIF, the set of accessible registers is limited compared to the regular VSPD operations. Support ISP interfacing in the rpf and wpf entities by checking if the pipe features an IIF instance and writing only the relevant registers.

2025-05-02	media: renesas: vsp1: Add support IIF ISP Interface	Jacopo Mondi
	The IIF (ISP InterFace) is a VSP2 function that transfers data to the ISP by reading from external memory through two RPF instances. Add support for it in the vsp1 driver by introducing a new entity type. The sole required operation is to enable the IIF function during configure_stream().
