While I'm preparing v2, there is a most important question has arisen.

Do we have any evidence of NXP5440 (ACPI ID) in *real* world?

To me it (the ID itself) sounds artificial and wilfully invented. In
case I'm right it must be removed from the driver. Otherwise, I would
like to see documentation or alike with DSDT excerpt and model of the
real device which has it.
