May I ask why you're creating an immutable branch of all this contents?

We should get the dts/dtsi contents like usual from any maintainer;
just the DT updates in a branch.

Sometimes (but less and less due to us discouraging the use) we need
an immutable branch that includes dt-include updates. But I don't see
any of those in this contents.

I.e. I guess I can see the need between mfd and downstream trees
(iio/pwm), but not the DTS contents at this time. Or am I missing
something here?

I agree with you.  However, since one of the STM32 Maintainers Acked
the DTS patches, and the other one hasn't been heard from for months,
I took that to mean he wanted me to apply and take them through the
MFD tree.

A misunderstanding or misaction perhaps, but this is the normal
assumption.
