Why?

Please explain what is the bug and how it manifests itself. Is one
property incorrect and other correct?

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.
Hint: there is no "boot"

at91-sama7g5ek.dtb: mcp16502@5b: regulators:VDD_(CORE|OTHER)|LDO[1-2]:
regulator-state-standby 'regulator-suspend-voltage' does not match any of
the regexes 'pinctrl-[0-9]+' from schema
$id: http://devicetree.org/schemas/regulator/microchip,mcp16502.yaml#

no property named regulator-suspend-voltage in
https://github.com/torvalds/linux/blob/master/Documentation/devicetree/bindings/regulator/regulator.yaml
so if it is using this property there will be no effect as it was expected in
https://github.com/torvalds/linux/commit/85b1304b9daa06367139b471789c7ddb76250b9f

The main reason is explained in the cover-letter but if you ask me to explain in each commit I will do it in next version.

Yes, in hurry I slipped that "boot" in subject.

Cover letter does not go to commit history. Each commit should explain
why you are doing it. Usually piece of the warning is quite
self-explanatory, thus one easy way to achieve the point - answer why.
