[PATCH 1/4] arm64: dts: qcom: sm8750: Add CDSP

[Krzysztof Kozlowski]

Add nodes for the CDSP and its SMP2P.  These are compatible with earlier
SM8650 with difference in one more interrupt.

Not great given the status = "fail" on MTP..

Luckily there are reports that all modems on recent boards crash (sm8550
and newer), so probably nothing wrong was in this DTS. :)

Well, someone will try it. Either it crashes or not. If it crashes, then
person will send report or patch to change it. If it does not, then it
will mean it is tested.

This is a shiny new platform, so no one expects this platform to work
flawlessly and no users are impacted by such untested code. Merging this
has only benefits: more test coverage by early adopters.

Best regards,
Krzysztof

Even 0x10000 (one less 0) according to downstream DTS. 0x100000 would be
entire touring qdsp6v7 map (1 MB).

However we always - sm8450, sm8550, sm8650 - map here 20 MB for some
reason. Any ideas? Let's correct all platforms to 0x100000?

For the record, there were no differences in downstream kernel.

Krzysztof

Oh, we all love to copy code, starting from sm8150, I think. Depends
which block we actually assign here - this should be 0x10000 (downstream
DTS) or 0x100000.

Older PIL remoteproc loaders (qcom_q6v5_adsp.c) seem to access only the
smaller 0x10000 region.

Best regards,
Krzysztof

SM8150 had it correct - 4040. All others are copy-paste. I'll do some
tests and send patches.

No clue. I made this comment based on what the computer told me.
Maybe some Q6 folks would know..

After we figure it out, sure

Do we have anyone looking into that?
