By default it acts as an output and signals specific events happening (e.g. change in State of Charge). While in shutdown mode it acts as an input and toggling it will make the sensor exit the mode. * - ``zephyr,lazy-load`` - ``boolean`` - .. code-block:: none Configuring the sensor can take a long time, using lazy loading we can delay until the first sample request and keep the boot time as short as possible. * - ``supply-gpios`` - ``phandle-array`` - .. code-block:: none GPIO specifier that controls power to the device. This property should be provided when the device has a dedicated switch that controls power to the device. The supply state is entirely the responsibility of the device driver. Contrast with vin-supply. * - ``vin-supply`` - ``phandle`` - .. code-block:: none Reference to the regulator that controls power to the device. The referenced devicetree node must have a regulator compatible. This property should be provided when device power is supplied by a shared regulator. The supply state is dependent on the request status of all devices fed by the regulator. Contrast with supply-gpios. If both properties are provided then the regulator must be requested before the supply GPIOS is set to an active state, and the supply GPIOS must be set to an inactive state before releasing the regulator. .. group-tab:: Deprecated node specific properties Deprecated properties not inherited from the base binding file. (None) .. group-tab:: Base properties Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the "ti,bq274xx" compatible. .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``reg`` - ``array`` - .. code-block:: none device address on i2c bus This property is **required**. See :ref:`dt-important-props` for more information. * - ``status`` - ``string`` - .. code-block:: none indicates the operational status of a device Legal values: ``'ok'``, ``'okay'``, ``'disabled'``, ``'reserved'``, ``'fail'``, ``'fail-sss'`` See :ref:`dt-important-props` for more information. * - ``compatible`` - ``string-array`` - .. code-block:: none compatible strings This property is **required**. See :ref:`dt-important-props` for more information. * - ``reg-names`` - ``string-array`` - .. code-block:: none name of each register space * - ``interrupts`` - ``array`` - .. code-block:: none interrupts for device See :ref:`dt-important-props` for more information. * - ``interrupts-extended`` - ``compound`` - .. code-block:: none extended interrupt specifier for device * - ``interrupt-names`` - ``string-array`` - .. code-block:: none name of each interrupt * - ``interrupt-parent`` - ``phandle`` - .. code-block:: none phandle to interrupt controller node * - ``label`` - ``string`` - .. code-block:: none Human readable string describing the device (used as device_get_binding() argument) See :ref:`dt-important-props` for more information. * - ``clocks`` - ``phandle-array`` - .. code-block:: none Clock gate information * - ``clock-names`` - ``string-array`` - .. code-block:: none name of each clock * - ``#address-cells`` - ``int`` - .. code-block:: none number of address cells in reg property * - ``#size-cells`` - ``int`` - .. code-block:: none number of size cells in reg property * - ``dmas`` - ``phandle-array`` - .. code-block:: none DMA channels specifiers * - ``dma-names`` - ``string-array`` - .. code-block:: none Provided names of DMA channel specifiers * - ``io-channels`` - ``phandle-array`` - .. code-block:: none IO channels specifiers * - ``io-channel-names`` - ``string-array`` - .. code-block:: none Provided names of IO channel specifiers * - ``mboxes`` - ``phandle-array`` - .. code-block:: none mailbox / IPM channels specifiers * - ``mbox-names`` - ``string-array`` - .. code-block:: none Provided names of mailbox / IPM channel specifiers * - ``wakeup-source`` - ``boolean`` - .. code-block:: none Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary. * - ``power-domain`` - ``phandle`` - .. code-block:: none Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
