| 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/arm64/boot/dts/freescale/imx95-pinfunc.h>. The last |
| integer CONFIG is the pad setting value like pull-up on this pin. |
| Please refer to i.MX95 Reference Manual for detailed CONFIG settings. |
