na_pio

When I read some driver code of led, I find the structrue na_pio was used, but I can't see any clew of including the relative .h file, so I wander why does this structrue can be used freely when writing drivers?

    take a look at your nios2_system.h. i guess you are including this file. Look for: 

    #ifndef __ASSEMBLY__# include <asm/pio_struct.h># endif
