Can't you rename the file "internally" so that users of the header still
only include asm/gpio.h?  Really at some point I want to see only such
an include for users of the gpio system, so why introduce such a detail
in all users now?

I.e. why not have a gpio.h which does a conditional include of
ppc4xx-gpio.h?

Thanks
  Detlev
