                Initial operating mode. The set of possible operating modes depends on the
                capabilities of every hardware so each device binding documentation
                explains which values the regulator supports.



         * - ``regulator-allowed-modes``
           - ``array``
           - .. code-block:: none

                List of operating modes that software is allowed to configure for the
                regulator at run-time. Elements may be specified in any order. The set of
                possible operating modes depends on the capabilities of every hardware so
                each device binding document explains which values the regulator supports.

                wake up the system.
