  Add the base DTSI files for QDU1000 and QRU1000 SoCs, including base
descriptions of CPUs, GCC, RPMHCC, QUP, TLMM, and interrupt-controller
to boot to shell with console on these SoCs.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC.  It might happen, that command when run on an older
kernel, gives you outdated entries.  Therefore please be sure you base
your patches on recent Linux kernel.

You should add here a specific compatible as well. Same in other places.
All places. I had impression we talked about this few times, so I don't
know what is missing on your side.

This must be:
"qcom,qdu1000-gpi-dma", "qcom,sm6350-gpi-dma"

Can we have some generic agreement where to put drive-strengths and bias?

Sure thing; we talked about this on a different patch.

Got it. I talked to Stephan and he said either your suggestion or just using
preexisting compatibles would be ok. I thought it might be cleaner to not
have the qdu compats, but I'm fine either way.

Not sure how much two-sense I have for the conversation at large, but generally I agree with Doug's
point in the first paragraph. Pulls for this soc are consistent across boards so I don't think it makes
sense to move them to the board files here. I vote that these stay here.

Coming back to this, it looks like this will fail dtb_check since compatible field is too long.
Is there an adjustment to the binding which needs to be made here?

Every compatible must be documented, so yes, bindings needs changes.

I'm not sure why this is being brought up again; we've already discussed this here
https://lore.kernel.org/all/9707bf67-1b22-8a77-7193-fc909b4f49de@quicinc.com/
Would you like to discuss this issue here, on the next version, or not at all?

On a side note, I'm uncomfortable with how our continued interactions are going
and do not believe this to be conductive to continued collaboration. I would ask that
we keep our correspondence polite and professional moving forward.

Thanks,
Melody

I have added Konrad and Bjorn is already there on the thread. Our 
understanding is that CCing maintainers comment is for next patch series 
after this one.

Bjorn, please check and comment on above? If requires we should start 
writing the guidelines for MSM boards since lot of comments are based on 
the experience or knowledge in the community Vs caught by tools - so it 
is easy to be missed by developers submitting new boards. Thoughts?

We use specific compats so that if it turns out this specific SoC (or 
rather the

bundled firmware) has some peculiar bugs, we can retroactively only 
apply them

to that specific SoC by adding the compatible somewhere in .c code if 
need be.

I agree with Doug on having 'generic' drive-strength. Moreover, maybe 
even adding some property like

bias-type = <NONE/PULL_DOWN/...> would be cool to make it more flexible 
so that we could trim off

A LOT of repeated lines (remember, most boards are more or less copies 
of the reference design for a

given platform like QRD or CRD) going forward.

BTW: you can feed git send-email with 
--cc-cmd='./scripts/get_maintainer.pl --norolestats' and

it'll pick the right people for you (most of the time, anyway).

Big yes! Some of the points should probably even be raised wrt the DT 
spec itself, such as property order.

A bit excessive, yes. If it's just a discussion and the issue has
already been raised, add the people and move on. OTOH, imagine having
to mention the same things multiple times a day in reviews. It is
tiring.

That uses git history which doesn't really work well IMO being on the
receiving end of those. I would suggest something like this in your
.gitconfig:

[sendemail.linux]
        tocmd =" scripts/get_maintainer.pl --nogit --nogit-fallback --nol"
        cccmd ="scripts/get_maintainer.pl --nogit --nogit-fallback --nom"
        confirm = always

Then you do just 'git send-email --identity=linux ...'

Or use b4 as it does the above and works better for series.

Some internal review or training for new contributors is needed IMO.
Some companies are required to have an known/experienced kernel
developer signoff on patches before they are submitted. I don't think
you want to get to that point.

Ideally, we should only be providing comments that can be referenced
to documentation (if the tooling can't address it). In this case, I
don't think the DT spec would be the right place property order. It's
just a convention for the schema format. However, often the
documentation we do have already isn't followed, so I'm not too
motivated to add more.

Huh so if I understand this correctly, like a generic QRD/CRD file which has the bias for specific pins?
That's a neat idea.

I will say it kinda seems like this is a larger conversation happening here. Does it make sense to submit
a next version with these pins as they are or wait until this larger conversation concludes?

Ok, this conversation seems to have stalled for now. Will submit v4 with changes except for this;
we'll see where this conversation lands.
