No, no. Stop doing random changes. NAK

Now you remove strict order (see writing bindings) and claim every
device like SM8550 ADSP PAS has any order.

And it is now de-synced with interrupts. Read writing bindings - this is
clearly described there at line 90!

You can only grow existing list.

So every device like SM8550 PAS has now four smem states... without any
explanation. Read writing bindings - what does it say?

"... and define constraints specific to the device."

"DO define properties in terms of constraints. How many entries? What are
 possible values? What is the order? All these constraints represent the ABI
  as well."

It is your homework to read the docs. Not mine.

If you want to change common list you must define strict constraints for
EVERY user.
