Hi Mark.
There is an even simpler solution.
For each arch that uses asm-generic/gpio.h add a line
to arch/$ARCH/include/asm/Kbuild like this:
generic-y += gpio.h
This will then make this arch pick up the asm-generic version when
you do #include <asm/gpio.h>.
And you avoid the kconfig games.
iFor the archs which require their own asm/gpio.h file - just
add it to the asm/ dir - and do not add the generic-y assignment.
