The TCON is a controller generating the timings to output videos signals,
acting like both a CRTC and an encoder.

It has two channels depending on the output, each channel being driven by
its own clock (and own clock controller).

Add a driver for the channel 1 clock.

Similar comments apply to patches 3 and 4. Was the same code
copy/pasted two more times and then changed to have different
values?
I don't really recall, but I probably used the same skeleton yeah.
Looks like we should consolidate all that stuff into something more
generic so that we don't have the same problems 3 times.
Does it?

They're both pretty different actually. One is a gate + mux + reset
(patch 3), the other one is actually a combination of two clocks, one
that is the parent of the other, the former being a gate + mux, the
latter a gate + div.

At least at the hardware level, they're very different, and adding
more code to deal with both case would complicate quite a lot the
probe code, for no real reasons.
