This looks like an unrelated change.
Hi Fabio,
Thanks for your reply. When compiling without "#include <common.h>", the following error will appear: In file included from ./arch/arm/include/asm/gpio.h:2, from drivers/gpio/adp5585_gpio.c:10: ./arch/arm/include/asm/arch/gpio.h:12:9: error: unknown type name ‘u32’ 12 | u32 gpio_pdor; | ^~~ ./arch/arm/include/asm/arch/gpio.h:13:9: error: unknown type name ‘u32’ 13 | u32 gpio_psor; | ^~~ ./arch/arm/include/asm/arch/gpio.h:14:9: error: unknown type name ‘u32’ 14 | u32 gpio_pcor; | ^~~ ./arch/arm/include/asm/arch/gpio.h:15:9: error: unknown type name ‘u32’ 15 | u32 gpio_ptor; | ^~~ ./arch/arm/include/asm/arch/gpio.h:16:9: error: unknown type name ‘u32’ 16 | u32 gpio_pdir; | ^~~ ./arch/arm/include/asm/arch/gpio.h:17:9: error: unknown type name ‘u32’ 17 | u32 gpio_pddr; | ^~~ ./arch/arm/include/asm/arch/gpio.h:18:9: error: unknown type name ‘u32’ 18 | u32 gpio_pidr; | ^~~ ./arch/arm/include/asm/arch/gpio.h:19:9: error: unknown type name ‘u8’ 19 | u8 gpio_pxdr[32];

Whatever change you need to make in arch/arm/include/asm/arch-imx9/gpio.h should be addressed by a separate patch.
The patch that adds support for a new GPIO expander chip should not touch any i.MX-specific header.
