I'd think that the targeted reader of that table is\nmore interested in \"What's supported on my favorite SoC\". The pipeline\nname and possibly the ISP name are internal tech details. If he/she is\nnot too tech savy he/she might even not be able to lookup the ISP name.\n\nSo I'd vote for actual SoC names, if the list is somehow manageable.\nThis would allow us to either keep columns together for multiple SoCs if\nthey are similar enough, or split into multiple columns if they are\ndifferent enough. E.g. the i.MX8MP has the dewarper and HDR stitching\nwhich makes an impact on the feature list.\n\nTrying to write my proposal for the header I realized that I have no\nidea which SoCs contain the Intel IPU3 which would actually be\ninteresting information.\n\nRaspberry Pi is a bit special in that it names a product, but the name\nis so well known that I feel it should be there. In the future I could\nimagine a product to SoC mapping table for that matter.\n\nSo my proposal is something like this:\n| Feature | i.MX8MP | RK3399, RK3288 | BCM2711/Raspberry Pi 4 | BCM2712/Raspberry Pi 5 | Intel SoCs with IPU3 | Renesas V2H/V2N* | Software ISP (CPU)** |\n\n* Based on the ARM Mali C55, therefore easily extendable to ...\n** Software ISP is supported on the following platforms: ...\n\nBest regards,\nStefan\n\n> \n> Thanks,\n> Jai\n> \n> > \n> > > +

But the\nBCM271x part numbers make it too verbose. I would guess most of the people\nknow it only as \"the chip on my Pi board\", so I feel like making an\nexception for Raspberry Pi's case and dropping the part number from the\ntable in v3.\n\nI'll send the v3 shortly so it can be picked before the release. We can\nmake tweaks later of course.\n\n> Best regards,\n> Stefan\n> \n\nThanks,\n Jai\n\n> > \n> > Thanks,\n> > Jai\n> > \n> > > \n> > > > +
