| * Freescale i.MX6 SLL IOMUX Controller |
| |
| Please refer to fsl,imx-pinctrl.txt in this directory for common binding part |
| and usage. |
| |
| Required properties: |
| - compatible: "fsl,imx6sll-iomuxc" |
| - 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 |
| imx6sll-pinfunc.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.MX6SLL |
| Reference Manual for detailed CONFIG settings. |
