+        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;
+        };
+    power-source:
+      enum: [0, 1]
+      description: |
+        GPIO Supply Voltage Select, Selects the voltage rail used for the pin.
+        0 or MAX32_VSEL_VDDIO
+        1 or MAX32_VSEL_VDDIOH
+    drive-strength:
+      default: 0
+      enum: [0, 1, 2, 3]
+      description: |
+        There are 4 drive strength mode.
+        Mode 0: 1mA
+        Mode 1: 2mA
+        Mode 2: 4mA
+        Mode 3: 8mA
+        Default GPIO output drive strength is mode 0 for MAX32 MCUs.
