   34           each entry consists of 6 integers and represents the mux and config
   35           setting for one pin. The first 5 integers <mux_reg conf_reg input_reg
   36           mux_val input_val> are specified using a PIN_FUNC_ID macro, which can
   37           be found in <arch/arm64/boot/dts/freescale/imx8mq-pinfunc.h>. The last
   38           integer CONFIG is the pad setting value like pull-up on this pin. Please
   39           refer to i.MX8M Quad Reference Manual for detailed CONFIG settings.
