          each entry consists of 6 integers and represents the mux and config

29
          setting for one pin. The first 5 integers <mux_reg conf_reg input_reg

30
          mux_val input_val> are specified using a PIN_FUNC_ID macro, which can

31
          be found in <arch/arm64/boot/dts/freescale/imx95-pinfunc.h>. The last

32
          integer CONFIG is the pad setting value like pull-up on this pin.

33
          Please refer to i.MX95 Reference Manual for detailed CONFIG settings.
