Hi grayli_wang

>#define DSRC_PRI_RSTn IMX_GPIO_NR(4, 22)

seems this pad (LSIO_GPIO4_IO22) already defined in dts:

pinctrl_usdhc2_gpio: usdhc2gpiogrp {

SC_P_USDHC1_CD_B_LSIO_GPIO4_IO22 0x00000021

https://source.codeaurora.org/external/imx/uboot-imx/tree/arch/arm/dts/fsl-imx8qxp-mek.dts?h=imx_v20...

Best regards
