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

                Determines the division ratio of a kernel clock pre-scaler
                producing UCPD peripheral clock (ucpd_clk). It is recommended
                to use the pre-scaler so as to set the ucpd_clk frequency in
                the range from 6 to 9 MHz.

                Determines the division ratio of a ucpd_clk divider producing
                inter-frame gap timer clock (tInterFrameGap).
                The division ratio 15 is to apply for Tx clock at the USB PD 2.0
                specification nominal value.

             Default value: ``8``

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

                Determines the division ratio of a ucpd_clk divider producing

                When this property is provided a specific flag is set into the
                device that tells the system that the device is capable of
                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.

                The device will be notified when the power domain it belongs to is either
