Hello, A preprocessor symbol like “CONFIG_GENERIC_PINCTRL_GROUPS” was introduced by the commit c033a718f615b6b3ddc83ce3e0a217c30bd09cb5 (“pinctrl: stricten up generic group code”) on 2017-01-03. Some functions are only available then when this macro is defined. I have got the impression that the corresponding programming interface is used by the source file “drivers/pinctrl/freescale/pinctrl-imx.c” unconditionally. How do you think about to extend specifications for conditional compilation there?
