   35           each entry consists of 6 integers and represents the mux and config
   36           setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
   37           mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
   38           be found in <arch/arm/boot/dts/imxrt1170-pinfunc.h>. The last
   39           integer CONFIG is the pad setting value like pull-up on this pin. Please
   40           refer to i.MXRT1170 Reference Manual for detailed CONFIG settings.
