Hi Jhpark_vine,

The code you get from Pin Mux tool cannot be directly integrated into u-boot and linux bsp. The following information and steps are for your reference:
1. u-boot
--device tree: uboot-imx/arch/arm/dts/imx8mq-evk.dts
You need to modify this device tree according to the files you get.
--Pin MUX Header file:
uboot-imx/include/dt-bindings/pinctrl/pins-imx8mq.h
You need to find the corresponding reuse definition according to the obtained file and add it to imx8mq-evk.dts.
2.linux BSP
--device tree:
linux-imx/arch/arm64/boot/dts/freescale/imx8mq-evk.dts
---Pin Mux header file:
linux-imx/arch/arm64/boot/dts/freescale/imx8mq-pinfunc.h
Modify dts according to the definition of this file.

Have a nice day!

B.R,

Weidong
