Hello, This series adds support for V3U (r8a779a0) to the R-Car VIN driver. The V3U SoC is different from other Renesas SoCs as a new IP block (the ISP channel selector) is added between the CSI-2 receiver and the VIN modules. This new ISP IP deals with CSI-2 channel filtering based on VC/DT which in turn makes the VIN drivers much simpler with regards to the media graph. But it also means the rcar-vin driver needs to support and generate both the generic Gen3 MC-graph and the specific V3U MC-graph. The rcar-vin driver intertwines the VIN group concept and the usage of the media graph into a single implementation. This needs to be broken apart before the new V3U support can be added. The first 01/11 - 10/11 patches deals with this separation and its fallout. Fortunately patch 11/11 after all that preparation work is quiet simple and straight forward when adding the V3U support. There is a large patch (10/11) in the series, reviewers please fear not it only moves blocks of code around verbatim. While working on this series it have become even more apparent to me that the VIN group concept probably should be replaced with something like the Media Device Allocator API once it learns how to work with DT. This series separation of the two VIN concepts is a good first step for me to hope to find time to dig into that. Updates to the DT bindings have been posted in a separate patch.
