1 | * Freescale IMX53 IOMUX Controller |
| 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,imx53-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 a | |
| 10 | pin working on a specific function, CONFIG is the pad setting value like | |
| 11 | pull-up for this pin. Please refer to imx53 datasheet for the valid pad | |
| 12 | config settings. | |
