| 2 | |
| 3 | Please refer to fsl,imx-pinctrl.txt in this directory for common binding part |
| 4 | and usage. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible: "fsl,vf610-iomuxc" |
| 8 | - fsl,pins: two integers array, represents a group of pins mux and config |
| 9 | setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is |
| 10 | a pin working on a specific function, CONFIG is the pad setting value |
| 11 | such as pull-up, speed, ode for this pin. Please refer to Vybrid VF610 |
| 12 | datasheet for the valid pad config settings. |
