      Properties not inherited from the base binding file.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``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.



         * - ``spi-max-frequency``
           - ``int``
           - .. code-block:: none

                Maximum clock frequency of device's SPI interface in Hz


             This property is **required**.

         * - ``duplex``
           - ``int``
           - .. code-block:: none

                Duplex mode, full or half. By default it's always full duplex thus 0
                as this is, by far, the most common mode.
                Use the macros not the actual enum value, here is the concordance
                list (see dt-bindings/spi/spi.h)
                  0    SPI_FULL_DUPLEX
                  2048 SPI_HALF_DUPLEX



             Legal values: ``0``, ``2048``

         * - ``frame-format``
           - ``int``
           - .. code-block:: none

                Motorola or TI frame format. By default it's always Motorola's,
                thus 0 as this is, by far, the most common format.
                Use the macros not the actual enum value, here is the concordance
                list (see dt-bindings/spi/spi.h)
                  0     SPI_FRAME_FORMAT_MOTOROLA
                  32768 SPI_FRAME_FORMAT_TI



             Legal values: ``0``, ``32768``

         * - ``spi-cpol``
           - ``boolean``
           - .. code-block:: none

                SPI clock polarity which indicates the clock idle state.
                If it is used, the clock idle state is logic high; otherwise, low.



         * - ``spi-cpha``
           - ``boolean``
           - .. code-block:: none

                SPI clock phase that indicates on which edge data is sampled.
                If it is used, data is sampled on the second edge; otherwise, on the first edge.



         * - ``spi-hold-cs``
           - ``boolean``
           - .. code-block:: none

                In some cases, it is necessary for the master to manage SPI chip select
                under software control, so that multiple spi transactions can be performed
                without releasing it. A typical use case is variable length SPI packets
                where the first spi transaction reads the length and the second spi transaction
                reads length bytes.



         * - ``reset-gpios``
           - ``phandle-array``
           - .. code-block:: none

                GPIO connected to the modem's NRESET signal.

                This signal is open-drain, active-low as interpreted by the
                modem.



         * - ``busy-gpios``
           - ``phandle-array``
           - .. code-block:: none

         * - ``tx-enable-gpios``
           - ``phandle-array``
           - .. code-block:: none

                Antenna switch TX enable GPIO. If set, the driver tracks the
                state of the radio and controls the RF switch.



         * - ``rx-enable-gpios``
           - ``phandle-array``
           - .. code-block:: none

                Antenna switch RX enable GPIO. If set, the driver tracks the
                state of the radio and controls the RF switch.



         * - ``dio1-gpios``
           - ``phandle-array``
           - .. code-block:: none

                GPIO connected to DIO1. This GPIO will be used as a generic
                IRQ line from the chip.



         * - ``dio2-tx-enable``
           - ``boolean``
           - .. code-block:: none

                Use DIO2 to drive an RF switch selecting between the TX and RX
                paths. When enabled, DIO2 goes high when the chip is
                transmitting.



         * - ``dio3-tcxo-voltage``
           - ``int``
           - .. code-block:: none

                TCXO supply voltage controlled by DIO3 if present.

                See constants in dt-bindings/lora/sx126x.h.



         * - ``tcxo-power-startup-delay-ms``
           - ``int``
           - .. code-block:: none

           - ``int``
           - .. code-block:: none

                Maximum design power for the board's RFO_LP output matching network.

                The default setting of +14 dBm is a prevalent board configuration;
                however, for optimal performance, it is advisable to align the value with
                the board's RF design.

                See ST application note AN5457, chapter 5.1.2 for more information.
