I don't understand above commit msg. You add new compatible (new device)
but entire commit msg describes something else - some sort of a fix.

Heh? How? How adding a new driver needs fixes in the bindings?

This is just confusing.

That's not the way to add stable tag. See stable-kernel docs or any git

I don't understand also why you are adding clock to syscon. Clock
controllers have their own bindings.
