The spec you shared also defines device constraints (function 1). It
would be very 
useful if these constraints  could be parsed and compared against the
actual power 
states of devices on the system at least for debugging purposes.  I'm
not sure if you 
already had a plan for that in a future series.

For debug purpose, I have worked on a patch to dump the constraint
table in debugfs. But in the freeze path whether we meet the
constraints or not will not make any difference, other than for just
debugging.
