| 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/arm/boot/dts/imx6ul-pinfunc.h>. The last integer |
| CONFIG is the pad setting value like pull-up on this pin. Please |
| refer to i.MX6UL Reference Manual for detailed CONFIG settings. |
