Hi, it felt quite strange to me too, but that's what I thought you
meant with your previous suggestion [1].
To keep the required attribute I would be happy to reintroduce the
compatible here, in the regulator schema and the pmic dtsi.

Before I do that and resubmit, could you please help me understand
what you meant before?

Thank you!
