This page also describes child node properties in the following sections. .. tabs:: .. group-tab:: Node specific properties Properties not inherited from the base binding file. .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``enable-gpios`` - ``phandle-array`` - .. code-block:: none GPIO to use to enable/disable the controller. * - ``max_curr_opt`` - ``boolean`` - .. code-block:: none If enabled the maximum current output is set to 35 mA (25.5 mA else). * - ``log_scale_en`` - ``boolean`` - .. code-block:: none If enabled a logarithmic dimming scale curve is used for LED brightness control. A linear dimming scale curve is used else. * - ``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,lp5024" 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. This property is **deprecated**. * - ``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. * - ``zephyr,pm-device-runtime-auto`` - ``boolean`` - .. code-block:: none Automatically configure the device for runtime power management after the init function runs. Child node properties ===================== .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``label`` - ``string`` - .. code-block:: none Human readable string describing the LED This property is **required**. See :ref:`dt-important-props` for more information. * - ``index`` - ``int`` - .. code-block:: none Index of the LED on a controller. It can be used by drivers or applications to map a logical LED to its real position on the controller. For example, this allows to handle boards where the LEDs in an array/strip are not wired following the LED order of the controller. This property is **required**. * - ``color-mapping`` - ``array`` - .. code-block:: none Channel to color mapping of a multicolor LED. If a LED supports several colors, then the color-mapping property can be used to describe how the hardware channels and the colors are mapped. For example the channel to color mapping of RGB LEDs would be color-mapping = , , ; This property is **required**.
