I gave the others a brief look yesterday, I'll give a more in-depth look
and test today and send you my Tested-by and Reviewed-by.

Yeah, I just sent them upstream directly, since at this stage it wasn't a
SoC and board in wide enough circulation yet where a ready-to-use public
tree with all the in-flight patches made sense for the added chore of
rebasing things when new version of patch series get submitted imho.
Though since some of them have been languishing with no upstream response
for quite a while (*cough* TSADC *cough*) and some more RK3576 hardware,
notably the RADXA ROCK 4D, released in the meantime, it may make sense to
have them included in either our rockchip-release or rockchip-devel tree.

If you want to keep up to date on what's in flight, our RK3576 mainline
status matrix at https://col.la/rk3576status is usually kept fairly up to
date.

Hopefully once v6.16-rc1 drops, upstream maintainers/reviewers are in a
better position to take a look at some of those patch series again, I'll
resubmit them when the time comes. Nothing lights a fire like a RESEND
prefix in a series.
