<pre>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
<a href="https://bugzilla.kernel.org/show_bug.cgi?id=59841">https://bugzilla.kernel.org/show_bug.cgi?id=59841</a> 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.</pre>
