20 * Not all MHI state transitions are synchronous. Transitions like Linkdown,
22 * transition to a new state only if we're allowed to.
24 * Priority increases as we go down. For instance, from any state in L0, the
26 * this rule is state DISABLE. From DISABLE state we can only transition to
27 * POR state. Also, while in L2 state, user cannot jump back to previous
