1 * Freescale i.MX6 UltraLite IOMUX Controller
3 Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
7 - compatible: "fsl,imx6ul-iomuxc" for main IOMUX controller or
8 "fsl,imx6ull-iomuxc-snvs" for i.MX 6ULL's SNVS IOMUX controller.
9 - fsl,pins: each entry consists of 6 integers and represents the mux and config
10 setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
11 input_val> are specified using a PIN_FUNC_ID macro, which can be found in
12 imx6ul-pinfunc.h under device tree source folder. The last integer CONFIG is
13 the pad setting value like pull-up on this pin. Please refer to i.MX6 UltraLite
14 Reference Manual for detailed CONFIG settings.
