It should be no big deal to add extra information if required.  Given
how poor the upstreaming state is for HDMI I expect we'd get people
coming out of the woodwork if there were infrastructure, some of the
Exynos stuff looked similar to your situation for example.

Unless there is something obviously terrible about the hardware design
that I'm missing which means nobody else would ever have implemented
something like it I'd expect there will be at least one other system
that can make use of the code.
