I'm using of_mm_gpiochip_add to register the gpiochip.
In the platform's Kconfig only ARCH_WANT_OPTIONAL_GPIOLIB is needed, OF_GPIO seems to be selected automatically.
If I disable it in the .config and start "make menuconfig", it's selected again.
OF_GPIO seems to have the same state as GPIOLIB in menuconfig.
