Dynamic allocation should be fine, if you're using the new userspace ABI like tools/gpio/* or libgpiod and only that and in-kernel consumers, dynamic numbers are just fine. If you have old sysfs userspace that you need to support using the global GPIO numberspace, please look into ways to phase that out. Yours, Linus Walleij
