Certainly !

In /gpio/gpio.c the code
#include <bsp/gpio.h>
Now will point to generic GPIO API rather the bsp specific
(/include/gpio.h) .

And Generic API will generate error if not found certain macros like
 "BSP_GPIO_PIN_COUNT" .

So, I think the solution would be to change the generic gpio api header
file or bsp specific one (which looks not suitable) and give a try.
