Hi,

BTW: I did spend quite a bit of time getting a whole lot of HDMI clock
rates working on rk3288 in the Chrome OS kernel.  The main reason
these can't go upstream is that it depends on knowing that we'll be
able to fully control a PLL for HDMI and that's not guaranteed on
upstream.  I've tried to get folks interested in trying to solve that
problem in the past but never made any real progress.  :(

In any case, if I can ever answer any questions about the HDMI configs
I figured out to work on rk3288, please let me know.
