| Required properties: |
| - compatible: "fsl,imx8mm-iomuxc" for IOMUXC controller. |
| - fsl,pins: 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 |
| pins-imx8mm.h under device tree source folder. The last integer CONFIG is |
| the pad setting value like pull-up on this pin. Please refer to i.MX8M Mini |
| Reference Manual for detailed CONFIG settings. |
