It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

Not a bus.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see

You are repeating the same mistakes we fixed long time ago. This means
you started work from some downstream or old DTS. Don't. It's a waste of
time, also mine to tell you that we fixed all this.

Please start from scratch from upstream DTS and test your code before
sending.

That's not correct bootargs. earlyocon is debugging, so drop from
mainline code. console goes to stdout property.
root/PARTUIID is obviously not correct. My PARTUIID is different.

Drop entire chosen.

Undocumented. Please run scripts/checkpatch.pl and fix reported
warnings. Some warnings can be ignored, but the code here looks like it
needs a fix. Feel free to get in touch if the warning is not clear.

You MUST run checkpatch on your submissions. All of them.

Why? Was it disabled anywhere? Anyway, that's not even hardware.

I am not going to review the rest. Please read submitting patches and
carefully follow it. Run all standard tests on your code before sending
patches. There is no point in reviewer telling you something which
automated tools tell.
