Thanks for the explanation. It would be great if you could update your
board/beagle/mt9p031 branch and include the discussed changes.
Done. Could you please test it ?
Thanks for you help. There are no errors about the clocks or regulators
now but the rest does not work so well (everything mentioned below works
fine on my old 3.2.24 kernel):
1. The images streamed to omapdss using omap3-isp-live look like they
lost "synchronization" with a black bar horizontal bar jumping on the
screen and other such artifacts (it looks as if both width and height
were invalid). The framerate is about a half of what it should be.
Adjusting the camera iris changes the lightness of the image so the
whole pipeline is working to some extent (so these artifacts are not
just some random memory patterns).
The Register dumps are a little different between 3.2.24 and 3.10 [4].
2. When exiting from live the kernel hangs more often then not
(sometimes it is accompanied by "Unhandled fault: external abort on
non-linefetch" in "dispc_write_irqenable" in omapdss).
3. After setting up a simple pipeline using media-ctl[2] I get "CCDC
won't become idle errors". If I do this after running "live" I also get
(unless it hangs) the CCDC Register dump [1]. Otherwise I only get the
stream of kernel log messages without anything else from omap3isp.
4. I recreated the "live" pipeline (judging by the lack of differences
in media-ctl -p output [3]) and used yavta. I get the same hangs but
when I don't I can check the UYVY frames one by one. They look bad at
any stride (I dropped the UV components and tried to get some meaningful
output in the GIMP raw image data import dialog by adjustung the "width").
