Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597
Why this cannot be passed by phandle, just like all reserved regions?
From where do you take these protected heaps? Firmware? This would
explain why no relation is here (no probe ordering, no device links,
nothing connecting separate devices).
Best regards,
Krzysztof
