> Could you clarify a bit why need move this part code?
Please check the mail, I have replied it yestoday as below, the function needs
to use imx_pinctrl structure,
so it needs to be moved, otherwise, build will fail.
> Any reason to move this part of code?
It is because below function callback added in imx_pinctrl_soc_info structure
need to use imx_pinctrl, otherwise, build will fail.
+ void (*imx_pinctrl_parse_pin)(struct imx_pinctrl *ipctl,
