                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.

          Default GPIO output drive strength is mode 0 for MAX32 MCUs.
          For more information please take a look device user guide, datasheet.



       Legal values: ``0``, ``1``, ``2``, ``3``

   * - ``input-enable``
     - ``boolean``
     - .. code-block:: none

          enable input on pin (e.g. enable an input buffer, no effect on output)



   * - ``power-source``
     - ``int``
     - .. code-block:: none

          GPIO Supply Voltage Select, Selects the voltage rail used for the pin.
          0 or MAX32_VSEL_VDDIO
          1 or MAX32_VSEL_VDDIOH



       Legal values: ``0``, ``1``

   * - ``output-enable``
     - ``boolean``
     - .. code-block:: none

          enable output on a pin without actively driving it (e.g. enable an output
          buffer)



   * - ``output-low``
     - ``boolean``
     - .. code-block:: none

          set the pin to output mode with low level


   * - ``output-high``
     - ``boolean``
     - .. code-block:: none

          set the pin to output mode with high level


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

          Integer array, represents gpio pin number and mux setting.
          These defines are calculated as: (pin<<8 | port<<4 | function<<0)
          With:
          - port: The gpio port index (0, 1, ...)
          - pin: The pin offset within the port (0, 1, 2, ...)
          - function: The function number, can be:
          * 0 : GPIO
          * 1 : Alternate Function 1
          * 2 : Alternate Function 2
          * 3 : Alternate Function 3
          * 4 : Alternate Function 4
          In case selected pin function is GPIO, pin is statically configured as
          a plain input/output GPIO. Default configuration is input. Output value
          can be configured by adding 'ouptut-low' or 'output-high' properties
          to the pin configuration.

          To simplify the usage, macro is available to generate "pinmux" field.
          This macro is available here:
            -include/zephyr/dt-bindings/pinctrl/max32-pinctrl.h
          Some examples of macro usage:
          P0.9 set as alernate function 1
          {
            pinmux = <MAX32_PINMUX(0, 9, AF1)>;
          };
          P0.9 set as alernate function 2
          {
            pinmux = <MAX32_PINMUX(0, 9, AF2)>;
          };
          P0.9 set as GPIO output high
          {
            pinmux = <MAX32_PINMUX(0, 9, GPIO)>;
            output-high;
          };



       This property is **required**.
