1 * Freescale IMX8MQ IOMUX Controller
3 Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory
4 for common binding part and usage.
7 - compatible: "fsl,imx8mq-iomuxc"
8 - reg: should contain the base physical address and size of the iomuxc
11 Required properties in sub-nodes:
12 - fsl,pins: each entry consists of 6 integers and represents the mux and config
13 setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
14 input_val> are specified using a PIN_FUNC_ID macro, which can be found in
15 imx8mq-pinfunc.h under device tree source folder. The last integer CONFIG is
16 the pad setting value like pull-up on this pin. Please refer to i.MX8M Quad
17 Reference Manual for detailed CONFIG settings.
