37          each entry consists of 3 integers and represents the pin ID, the mux value
38          and pad setting for the pin. The first 2 integers - pin_id and mux_val - are
39          specified using a PIN_FUNC_ID macro, which can be found in
40          <include/dt-bindings/pinctrl/pads-imx8qxp.h>. The last integer is
41          the pad setting value like pull-up on this pin. Please refer to the
42          appropriate i.MX8 Reference Manual for detailed pad CONFIG settings.
