| * Freescale IMX50 IOMUX Controller |
| |
| Please refer to fsl,imx-pinctrl.txt in this directory for common binding part |
| and usage. |
| |
| Required properties: |
| - compatible: "fsl,imx50-iomuxc" |
| - fsl,pins: two integers array, represents a group of pins mux and config |
| setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is a |
| pin working on a specific function, CONFIG is the pad setting value like |
| pull-up for this pin. Please refer to imx50 datasheet for the valid pad |
| config settings. |
