Power State D1 is supported. Allows for lowest possible
power consuming state from which it can return to fully on
state within 10ms, excepting analog pass-through circuits
which must remain fully on.
Power State D0 is supported. Node power state is fully on.

Wake capability. Assuming the Wake Enable
Mask controls are enabled, GPIO's configured
as inputs can cause a wake (generate a
Status Change event on the link) when there
is a change in level on the pin.
Unsolicited Response capability. Assuming
the Unsolicited Enable Mask controls are
enabled, GPIO's configured as inputs can
generate an Unsolicited Response on the link
when there is a change in level on the pin.
