> However the imx pinctrl driver _absolutely_ needs this configuration to work.

Thanks for your explanation that the file “drivers/pinctrl/freescale/Kconfig”
will usually provide needed information for this software module.

Would it make sense to document such a requirement also by a preprocessor error
directive in the source file “drivers/pinctrl/freescale/pinctrl-imx.c”
for the special case if the macro “CONFIG_GENERIC_PINCTRL_GROUPS” would
accidentally not be defined?

Regards,
Markus
