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. * - ``drdy-gpios`` - ``phandle-array`` - .. code-block:: none DRDY pin This pin defaults to active high when produced by the sensor. The property value should ensure the flags properly describe the signal that is presented to the driver. * - ``odr`` - ``int`` - .. code-block:: none Specify the default output data rate expressed in samples per second (Hz). The default is the power-on reset value. - 0 # LPS22HH_DT_ODR_POWER_DOWN - 1 # LPS22HH_DT_ODR_1HZ - 2 # LPS22HH_DT_ODR_10HZ - 3 # LPS22HH_DT_ODR_25HZ - 4 # LPS22HH_DT_ODR_50HZ - 5 # LPS22HH_DT_ODR_75HZ - 6 # LPS22HH_DT_ODR_100HZ - 7 # LPS22HH_DT_ODR_200HZ Legal values: ``0``, ``1``, ``2``, ``3``, ``4``, ``5``, ``6``, ``7`` * - ``friendly-name`` - ``string`` - .. code-block:: none Human readable string describing the sensor. It can be used to distinguish multiple instances of the same model (e.g., lid accelerometer vs. base accelerometer in a laptop) to a host operating system. This property is defined in the Generic Sensor Property Usages of the HID Usage Tables specification (https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5). .. 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 "st,lps22hh" compatible. .. list-table:: :widths: 1 1 4 :header-rows: 1 * - Name - Type - Details * - ``reg`` - ``array`` - .. code-block:: none Contains 3 fields. For I3C devices, the 3 fields are static address, first half of Provisioned ID, and the second half of the Provisioned ID. 1. The static address can be assigned to be the target device's dynamic address before Dynamic Address Assignment (DAA) starts. Can be zero if static address is not used, and target address is determined via DAA. 2. First half of the Provisioned ID contains the manufacturer ID left-shifted by 1, where the manufacturer ID is the bits 33-47 (zero-based) of the 48-bit Provisioned ID. 3. Second half of the Provisioned ID contains the combination of the part ID (bits 16-31 of the Provisioned ID) left-shifted by 16, and the instance ID (bits 12-15 of the Provisioned ID) left-shifted by 12. Basically, this is the lower 32 bits of the Provisioned ID. Note that the DT node of a I3C target device should be in format "@
", e.g. "sensor@4200001234012345678", where the PID part is expanded to be a 64-bit integer. For I2C devices, the 3 fields are static address, 0x00, and value of the Legacy Virtual Register (LVR). 1. 7-bit address of the I2C device. (Note that 10-bit addressing is not supported.) 2. Always 0x00. 3. LVR describes the I2C device where, * bit[31:8]: unused. * bit[7:5]: I2C device index: * Index 0: I2C device has a 50 ns spike filter where it is not affected by high frequency on SCL. * Index 1: I2C device does not have a 50 ns spike filter but can work with high frequency on SCL. * Index 2: I2C device does not have a 50 ns spike filter and cannot work with high frequency on SCL. * Other values are reserved. * bit[4]: I2C mode indicator: * 0: FM+ mode * 1: FM mode * bit[3:0]: reserved. The DT node of a I2C device should be in format "@
", e.g. "sensor@5000000000000000FF", where the middle 0x00 and LVR are both expanded to 32-bit integers. 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**.

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.
