That's uno reverse card. I do not have to prove why these are different.
You need to prove why imx95 are bindings.

Yeah, entirely different things. Like comparing apples and oranges.

No, the SCMI cannot be used in the drivers, because these are not
abstract IDs mapping between driver and DTS.

You just pointed out difference - no usage in drivers, no ABI!

Instead of playing this "I found this code somewhere, so I can do
whatever the same" answer the first implied question - why these are
bindings? Provide arguments what do they bind.
