| 6 | Required properties: | |
| 7 | - compatible: "fsl,imx6ul-iomuxc" | |
| 8 | - fsl,pins: each entry consists of 6 integers and represents the mux and config | |
| 9 | setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val | |
| 10 | input_val> are specified using a PIN_FUNC_ID macro, which can be found in | |
| 11 | imx6ul-pinfunc.h under device tree source folder. The last integer CONFIG is | |
| 12 | the pad setting value like pull-up on this pin. Please refer to i.MX6 UltraLite | |
| 13 | Reference Manual for detailed CONFIG settings. | |
