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.
Sorry I don't really understand that. For me fdtdec.c has #include
<asm-generic/gpio.h> and that is enough to get gpio_request(). Can you please
advise what warning you see and for what board?
Microblaze:
lib/libgeneric.o: In function `fdtdec_setup_gpio':
/mnt/projects/u-boot/lib/fdtdec.c:477: undefined reference to `gpio_request'
The same error will be for nios2, openrisc and blackfin because they define
gpio_request as static inline function in arch/<arch>/include/asm/gpio.h
Because I think there should be asm/gpio.h included which can include
asm-generic/gpio.h
(this is arm case).
