1 | * Freescale IMX6 SoloLite 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,imx6sl-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 imx6sl datasheet for the valid pad | |
12 | config settings. | |
