The Tosa (Sharp SL-C6000x) target is the last remaining user of gpiochip_reserve(). I would like to get rid of this function as part of my project to totally remove the big static gpio_desc[] array of gpiolib. Patches that achieve this are written and working, but the presence of gpiochip_reserve() makes it necessary to maintain a list of "reserved" ranges in the GPIO space, which complexifies code that would be much simpler otherwise. Even for Tosa the use of gpiochip_reserve() does not seem necessary - all GPIO controllers have their own base GPIO set AFAICT, so there should be no need to use it. And without any user in the kernel, there should be no reason to keep this function. If Dmitri could give his Acked-by or Tested-by and one of the GPIO maintainers merge this series, I could go ahead with the deeper changes to gpiolib.
