             This property is **required**.

         * - ``pf1550,system-voltage-min-threshold-microvolt``
           - ``int``
           - .. code-block:: none

                System voltage minimum threshold.



             This property is **required**.

             Legal values: ``3500000``, ``3700000``, ``4300000``

         * - ``pf1550,thermistor-monitoring-mode``
           - ``string``
           - .. code-block:: none

                Thermistor monitoring mode.
                Refer to ThrmCfg register description and Table 2 for details.



             This property is **required**.

             Legal values: ``'disabled'``, ``'thermistor'``, ``'JEITA-1'``, ``'JEITA-2'``

         * - ``pf1550,int-gpios``
           - ``phandle-array``

         * - ``pf1550,led-behaviour``
           - ``string``
           - .. code-block:: none

                Behaviour for charger LED.



             This property is **required**.

             Legal values: ``'on-in-charging-flash-in-fault'``, ``'flash-in-charging-on-in-fault'``, ``'manual-off'``

           - ``string``
           - .. code-block:: none

                This describes the chemical technology of the battery. The "lithium-ion" value is a blanket type for all lithium-ion batteries. If the specific chemistry is unknown, this value can be used instead of the precise "lithium-ion-X" options.


             Legal values: ``'nickel-cadmium'``, ``'nickel-metal-hydride'``, ``'lithium-ion'``, ``'lithium-ion-polymer'``, ``'lithium-ion-iron-phosphate'``, ``'lithium-ion-manganese-oxide'``

         * - ``ocv-capacity-table-0``
           - ``array``
           - .. code-block:: none

                An array providing the open circuit voltage (OCV) , which is used to look
                up battery capacity according to current OCV value. The OCV unit is
                microvolts.

                Unlike the linux equivalent this array is required to be 11 elements
                long, representing the voltages for 0-100% charge in 10% steps.



         * - ``charge-full-design-microamp-hours``
           - ``int``
           - .. code-block:: none

                battery design capacity


         * - ``re-charge-voltage-microvolt``
           - ``int``
           - .. code-block:: none

                limit to automatically start charging again


         * - ``precharge-current-microamp``
           - ``int``
           - .. code-block:: none

                current for pre-charge phase


         * - ``charge-term-current-microamp``
           - ``int``
           - .. code-block:: none

                current for charge termination phase
