1* Freescale i.MX6 UltraLite IOMUX Controller 2 3Please refer to fsl,imx-pinctrl.txt in this directory for common binding part 4and usage. 5 6Required properties: 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.
