   44           setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
   45           mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
   46           be found in <arch/arm/boot/dts/imx7d-pinfunc.h>. The last integer
   47           CONFIG is the pad setting value like pull-up on this pin. Please
   48           refer to i.MX7D Reference Manual for detailed CONFIG settings.
