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