Yeah, I know, I'm even the one that introduced this in the first place
:)
I sent a patch earlier this week to remove it from the other DT.

Yes.

Strictly speaking, they do not control the same set of devices. I'd
prefer to have a different compatible in case we need to setup a
particular behaviour on a given SoC (for example, force out of reset a
particular device, even if no driver is actually using it), without
impacting the other.

But we will need to do that yes.

Hmmmm, I think I somehow overlooked the fact that the timer was there,
even though Chen-Yu said it. My bad :/
