--- Comment #21 from Jani Nikula <jani.nikula at intel.com> ---
Looking at the logs, the DP clock recovery seems to fail, but luckily it works
at channel eq phase... we've got something fishy there. Also seen in
https://bugzilla.kernel.org/show_bug.cgi?id=59841 but there channel eq fails
too with some bpp values.

I think we should get the link training fixed first, although AFAICT the
slowness isn't caused so much by the link training, but rather by the panel
power sequencing delays.
