Yes, nearly there. Just thought good to add a note that the representation
has no affinity towards any PSCI idle state mechanism(PC or OSI). So
that it's never assumed or misunderstood.

I understand your point. However, I think the following sentence still
makes sense (exist in the suggest change above).

"In PSCI firmware v1.0, the OS-Initiated mode is introduced. In order
to use it, the hierarchical representation must be used."

How about if I add: "For the default platform-coordinated mode, both
representations are viable options."

I would also add couple of things, how about this order:

In PSCI firmware v1.0, the OS-Initiated mode is introduced. However the
flattened vs hierarchical DT representation of power domains is orthogonal
to OS-Initiated vs platform-coordinated PSCI CPU suspend modes and
should be considered independent of each other.

The hierarchical representation helps and makes it easy to implement
OSI mode and OS implementations may choose to mandate it.

For the default platform-coordinated mode, both representations are
viable options.
