Need help in finding GPIO library for Orange Pi zero on linux-5.10.60 sources.

Hi all ,

 

I am trying to work with GPIO , on Orange Pi zero latest kernel image (linux-sunxi-5.10.60). In old kernel linux-3.4.114 there used to be  gpio_lib.h,gpio_lib.c  files which are for this purpose as I know.

Could someone help me find similar library in latest kernel sources.

 

thanks

I suspect it is    "drivers/pinctrl/sunxi/pinctrl-sunxi.h" , not tried yet. Correct  me know if I am wrong.
