AFAIR the ISP itself can only output either Bayer or YUV 4:2:2. The resizer can take YUV 4:2:2 at its input and output YUV 4:4:4, 4:2:2 and 4:2:0. Bayer capture is handled with resizer bypass mode. We haven't tested that, but if implemented, it should probably be done by exposing a link between the ISP entity and a video node directly, without the resizer involved. WDYT?
