The Tegra186 and Tegra194 contain a CEC controller that is identical to
that found in earlier generations. Document the compatible strings for
these newer chips.

If identical, why don't you have a fallback compatible?

That's a good point. I think it would be fine to always fall back to the
nvidia,tegra20-cec compatible.
