Thank you for pointing this out and for sharing the build warnings.

I will review the reported DT issues, verify the root causes, and address
them accordingly. The fixes will be included in the next revision of the
patch series.

I rechecked this 'psci: 'reboot-mode' does not match any of the regexes'
issue on my side using linux-next tag 'next-20260223', but I
was not able to reproduce the reported error.

Could you please share the exact tree/commit and configuration you used
for the build? I would like to align my environment and investigate this
further.

The missing clock-names property issue is already being addressed by the
following patch:
https://lore.kernel.org/linux-arm-msm/e025b1b4-8f5c-4fd2-853e-56b89f1f8e79@xxxxxxxxxxxxxxxx/
I will reference this dependency in the next revision of my patch series
(commit notes)to ensure the build and schema checks are aligned.

I rechecked the 'Unevaluated properties are not allowed ('cooling' was unexpected)'
issue locally using linux-next tag 'next-20260223', but I was not able to reproduce
this issue.
Additionally, I am not introducing or modifying any cooling-related nodes
in my DTS/DT overlay.The cooling property appears to originate from the base
talos.dtsi, and is not touched or referenced by my patch series.
