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

         * - Name
           - Type
           - Details

         * - ``pinctrl-0``
           - ``phandles``
           - .. code-block:: none

                PORT pin configuration for the PWM signal.
                We expect that the phandles will reference pinctrl nodes. These
                nodes will have a nodelabel that matches the Infineon SoC Pinctrl
                defines and have following
                format: p<port>_<pin>_<peripheral inst>_<signal>.

                Examples:
                  pinctrl-0 = <&p1_1_pwm0_0>;



             This property is **required**.

         * - ``pinctrl-names``
           - ``string-array``
           - .. code-block:: none

                Names for the provided states. The number of names needs to match the
                number of states.



             This property is **required**.

         * - ``resolution``

         * - ``divider-type``
           - ``int``
           - .. code-block:: none

                Specifies which type of divider to use.
                Defined by cy_en_divider_types_t in cy_sysclk.h.

                Specifies which divider of the selected type to configure.



             This property is **required**.

         * - ``divider-val``
           - ``int``
           - .. code-block:: none

                Causes integer division of (divider value + 1), or division by 1 to 256
                (8-bit divider) or 1 to 65536 (16-bit divider).



             This property is **required**.

         * - ``#pwm-cells``
           - ``int``

                Number of items to expect in a PWM
                - channel of the timer used for PWM (not used)
                - period to set in ns
                - flags: standard flags like PWM_POLARITY_NORMAL



             This property is **required**.

             Constant value: ``3``

         * - ``pinctrl-1``
           - ``phandles``
           - .. code-block:: none

           - ``phandles``
           - .. code-block:: none

                Pin configuration/s for the fourth state. See pinctrl-0.



         * - ``pinctrl-4``
           - ``phandles``

   .. 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
