I think it would be benficient to switch to these fields, because then
the .clock field (dot/pixelclock) is not abused to contain what I guess
is the desires hs_rate.

That just means "clock it as high as the panel can take".

Normally that would come from the vendor datasheet of
the panel.

If you don't have the datasheet, whatever you use in the vendor
tree is fine, I suppose what is currently in .clock is fine.
