Also include arch specific gpio.h which can contain

Can you not instead support the generic functions? What are you missing
from from there that fdtdec.c needs?
OK. The problem is with fdtdec_setup_gpio function where you called
gpio_request which
is gpio specific function which you haven't included.
The most archs have this defined in arch/<cpuname>/include/asm/__gpio.h.
This is there in my tree. Please see commit:
5f533aeb gpio: Modify common gpio.h to more closely match Linux
This is generic gpio cleanup but I don't think this is the same thing.
I think you should get some warnings for fdtdec compilation around missing
gpio_request
declaration or you include gpio.h in any other header file which is in
fdtdec.c/h.
Thanks,
Michal
