* Freescale IMX8MN IOMUX Controller
Please refer to fsl,imx-pinctrl.txt and pinctrl-bindings.txt in this directory
for common binding part and usage.
Required properties:
- compatible: "fsl,imx8mn-iomuxc"
- reg: should contain the base physical address and size of the iomuxc
registers.
Required properties in sub-nodes:
- 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
<arch/arm64/boot/dts/freescale/imx8mn-pinfunc.h>. The last integer CONFIG is
the pad setting value like pull-up on this pin. Please refer to i.MX8M Nano
Reference Manual for detailed CONFIG settings.
Examples:
&uart1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_uart1>;
};
iomuxc: pinctrl@30330000 {
compatible = "fsl,imx8mn-iomuxc";
reg = <0x0 0x30330000 0x0 0x10000>;
pinctrl_uart1: uart1grp {
fsl,pins = <
