"cdns" is vendor prefix. Use SoCs-specific compatibles.

The StarFive SoC contains cdns dsi ip inside. It did not create cdns block. Sorry about that.
It will be fixed by using SoCs-specific compatibles.

You need to restrict other variants, because you just relaxed several
properties for everyone...
