| 35 | each entry consists of 6 integers and represents the mux and config |
| 36 | setting for one pin. The first 5 integers <mux_reg conf_reg input_reg |
| 37 | mux_val input_val> are specified using a PIN_FUNC_ID macro, which can |
| 38 | be found in <arch/arm/boot/dts/imxrt1050-pinfunc.h>. The last |
| 39 | integer CONFIG is the pad setting value like pull-up on this pin. Please |
| 40 | refer to i.MXRT1050 Reference Manual for detailed CONFIG settings. |
