We do not break userspace, so I guess we should put in some hack to keep the base 0 on ipq8064 then, but as pointed out by Bjorn there will be problems when we get multiple gpiochips in later platforms so it is just a stopgap solution. Have you looked into using the new character device with your userspace, either as shown in the examples: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/gpio or using libgpiod: https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/ Yours, Linus Walleij
