- * Freescale i.MX6 UltraLite IOMUX Controller
- Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
- and usage.
- Required properties:
- - compatible: "fsl,imx6ul-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
- imx6ul-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.MX6 UltraLite
- Reference Manual for detailed CONFIG settings.
