Without CONFIG_OF, we can run into a build error:

drivers/gpu/drm/tegra/dpaux.c:378:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function); did you mean 'pinconf_generic_params'?
  .dt_node_to_map = pinconf_generic_dt_node_to_map_group,
                    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                    pinconf_generic_params
drivers/gpu/drm/tegra/dpaux.c:379:17: error: 'pinconf_generic_dt_free_map' undeclared here (not in a function); did you mean 'pinconf_generic_params'?

This adds an explicit dependency.

Thanks Arnd. I am curious if it can still fail if PINCTRL is not
selected in whatever config you are using?

That said ...

I have not run into other those problems in many randconfig builds.
Looking at the driver now, I see it has an "#ifdef CONFIG_GENERIC_PINCONF"
to handle that case.
