| 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/imx8mn-pinfunc.h>. The last | |
| 38 | integer CONFIG is the pad setting value like pull-up on this pin. Please | |
| 39 | refer to i.MX8M Nano Reference Manual for detailed CONFIG settings. | |
