Few more small nits.

Also to note, I'd appreciate if you separate upstreamable and not-yet-upstreamable commits when you work on this. That is, keep addition of display and other nodes that rely on not-yet-upstream drivers as separate commits, and anything that could land upstream squash into a single "Add initial devicetree" commit. (bindings are separate commit that should be first, keep it as is)

I'd also appreciate if you can fill in a short blurb into the bindings/initial dt commit messages, see i.e. this series for an example.

When you're done I'd like to ask you to submit upstreamable part upstream, so I can backport it into our tree and not rebase forever, which would help with maintenance a lot. Of course we will still provide you with preliminary review comments based on what we expect upstream to think while you continue to work in this PR.

What about the WCN3620 module? You do need firmware for that but the drivers are in the kernel right? So it doesn't need an extra commit?

With a few exceptions, only display panel is non-upstreamable. You can check upstream msm8916 devices for examples of what's "upstreamable" and git history of this repo for examples of something that we didn't/couldn't upstream yet.

Oh sorry the incorrect formating and notes I left, I'm gonna clean them up but right now I'm still struggling with the audio

[stephan-gh]

@myryk31415 What is the current state of this? Are you still working on more features for the device? Could you rebase and re-test this on top of the latest msm8916/v6.17-rc6 branch so we can merge it?

[myryk31415]

I tried to get audio working but rarely spend time on it.
Will try to rebase and test this week.

[myryk31415]

Can i change the branch I want to merge to? Since its rebased to 6.17

Edit: nvm found it

[myryk31415]

Also I have a proximity sensor with compatible string "stk,stk3x1x" in the downstream devicetree, I set it to "sensortek,stk3310" for now. Is there a way to find out the exact model withouth the schematics / taking it apart?
