[PATCH 0/7] Add support for the Axis ARTPEC-9 SoC
Posted by Ravi Patel 2 weeks, 1 day ago 
Add basic support for the Axis ARTPEC-9 SoC which contains
6-core Cortex-A55 CPU and other several IPs. This SoC is an
Axis-designed chipset used in surveillance camera products.

This ARTPEC-9 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

This patch series includes below changes:
- CMU (Clock Management Unit) driver and its bindings (patch #1 to #3)
- PMU bindings (patch #4)
- Basic Device Tree for ARTPEC-9 SoC and boards (patch #5 to #7)

The patch series has been tested on the ARTPEC-9 EVB with
Linux Samsung SoC tree (for-next branch) and intended
to be merged via the `arm-soc` tree.

NOTE: This patch series is dependent on following floating patches:

NAK, sorry, DTS cannot depend on the drivers. Please decouple the
dependencies.

Maybe you wanted to point me where the bindings are, but then say so.

Ok, so you want patch #1 - #5 in separate series and #6 - #7 (DTS patches) in another series.
Can you please review the patches, I will address review comments in v2 (if any) itself.

Yes, these dependencies are for bindings related.

Thanks,
Ravi

No, I meant above dependencies. You said that these patchset, including
DTS, depends on above. Above are drivers and that's a no go. I said it
multiple times already in various occasions.

Patchset should be organized per maintainers subsystem, but that's
different question.

> Can you please review the patches, I will address review comments in v2 (if any) itself.

As mentioned in other threads, I closed my tree a week ago (if you are
surprised, notice kernel cycles and development process), so review will
happen a bit later.

So not really a dependency so again: just provide links to the bindings.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250917 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
