Hello Krzysztof,

also thanks for the feedback on this one.

Short note: I did that prior submitting, but I did it directly for the
yaml-file and not for the directory - Those do not look the same
regarding their prefix scheme.

I will change it for my v2 and use a subject like for the directory.

I am a bit lost on that one to be honest.

The only other instances where a "priority" for restart handling is
described are "gpio-poweroff.yaml" and "syscon-reboot.yaml". These files
are dedicated documentation for the reset bindings, so I tried to
transfer the respective entry over for my commit.

Do you suggest I should replace

+  priority:
+    $ref: /schemas/power/reset/restart-handler.yaml#

with

+allOf:
+  - $ref: /schemas/power/reset/restart-handler.yaml#

in order to properly include the context for the restart handling?
Running dt_binding_check does not indicate an issue with any of those two.

You mean by adding to the "description" part of the file?


Kind regards,
Holger
