1. 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

2. Start sentences with capital letters. LDO is acronym.

3. Constraints already tell you that, don't they? Explain why they are
not enough and you need new property.

Wrap according to Linux style (as expressed in Linux coding style document).
