I found none for now, and I am not someone from Rockchip, thus don't
know whether they have a plan to make it public, either. But there has
been some devices shipping it already and getting them mainlined will
be a neat thing.

Just FYI, the vendor kernel is available here[1] on the "develop-5.10"
branch.
