Or do you mean "R-Car V3U and Gen 4 SoCs"? Despite the name, R-Car V3U is the first member of the R-Car Gen4 family... https://www.renesas.com/us/en/products/automotive-products/automotive-system-chips-socs/r-car-v3u-best-class-r-car-v3u-asil-d-system-chip-automated-driving > > Is there anything that might be SoC-specific? > > If not, perhaps the time is ripe for a family-specific compatible value? > > At least v3u and v4h DSIs are slightly different. Well, the DSI IP block > itself looks the same, but the PLL and PHY are different. I noticed, when I saw the dsi-csi2 driver changes. So no family-specific compatible value is needed.
