If you mean making the option invisible in menuconfig, it can be done by simply removing the prompt message "NXP S32 Common .." from the bool type line. Although it will disappear from menuconfig but it can be automatically selected once the config PINCTRL_S32G is set to "y" due to its "select" option. > The alternative would be to leave it and have S32G depend on it, creating a > submenu structure, but that would then still allow to build the driver core > without any users. > > > + > > +config PINCTRL_S32G > > + depends on ARCH_S32 && OF > > + bool "NXP S32G pinctrl driver" > > + select PINCTRL_S32CC > > + help > > + Say Y here to enable the pinctrl driver for NXP 32G family SoCs > > s/32G/S32G/ > Will fix it in v3.
