Given that it worked with 6.0 but no more with 6.1-1~exp1 which I assume is a 
self-built kernel from current master, it seems more likely to be an upstream 
issue/regression.

In the linux-amlogic post [0] it was tested with 6.1-rc8.
https://tracker.debian.org/pkg/linux shows there have been several uploads of 
6.1-rcX to experimental, so could you test those first?

I just noticed the following part from that linux-amlogic post:

That path doesn't seem to exist anymore, but got redirected to 'just' the 
master branch and noticed the latest commit "update patches from khadas".
When I looked into that, I saw there were a LOT of additional patches :-O
https://salsa.debian.org/zhangn1985/linux/-/tree/master/debian/patches/
features/khadas

The test I suggested in my previous reply would still be useful, but it could 
also be that your patch-set is at fault.
