* Whether the DMA of frames to memory actually happens, regardless of (lack of) emission of the interrupt that tells us when said DMA finishes a frame.

* Whether the regulator messages we see during boot are actually significant. I don't know enough about the Linux regulator framework to say whether these being not-found means power is not correctly supplied, or if Linux just isn't being properly informed of the power supply requirements for precise tracking/power-saving when the camera is off.

Turns out, the .dts had the wrong ISP connected to the sensor!
Apply [https://github.com/megous/linux/commit/9afd884f8b36121fb6097e77b6d35fe46ab48ad9 this commit] ([https://github.com/megous/linux/commit/9afd884f8b36121fb6097e77b6d35fe46ab48ad9.patch patch]) to your kernel tree, rebuild, and reinstall. Now, the following should produce an image (<code>frame.jpg</code>):

=== What's left? ===
libcamera and megapixels still don't work. Megapixels appears to need support for debayering YUYV, and both appear to be configuring the rkisp1 pipeline wrong.
