Description
***********



.. code-block:: none

   Bluetooth module that uses Ambiq's Bluetooth Host Controller Interface SPI
   driver (e.g. Apollo4 Blue Plus).

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

         * - Name
           - Type
           - Details

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

                This irq gpio is used to indicate there is packet ready to send to host
                from controller.



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

                This reset gpio is used to reset the Bluetooth controller.



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

                This clkreq gpio is used to send the XO32MHz clock request to host from
                controller. The host needs to enable XO32MHz when receiving low to high
                edge interrupts and disable XO32MHz when receiving high to low edge
                interrupts.





   .. 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 "ambiq,bt-hci-spi" compatible.
