So far I'm mostly using "pmbootstrap build --src" [1], which essentially
builds the pmOS kernel package but replaces the source with the tree I
point at. I keep thinking I should try envkernel.sh [2], which is
supposed to set up cross-compiling with the usual make flow. Maybe
that'd work with bindeb-pkg?

I don't know how well an unpatched mainline kernel would run, I'm
currently using megi's 6.7 tree [3] plus the pmOS patches as the basis
for my rtw88_8723cs development [4] (if you look at the history, it's
v6.7 -> orangepi-6.7 -> pmos-6.7 -> rtw88_8723cs). I know megi's kernel
has some DTS patches but haven't looked too deeply into the changes,
maybe some could be upstreamed together with the camera part.
