   37           each entry consists of 6 integers and represents the mux and config
   38           setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
   39           mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
   40           be found in <arch/arm64/boot/dts/freescale/imx8mp-pinfunc.h>. The last
   41           integer CONFIG is the pad setting value like pull-up on this pin. Please
   42           refer to i.MX8M Plus Reference Manual for detailed CONFIG settings.
