I see.
The 'select CAN_SOFTING' was introduced because it makes no sense to
have CAN_SOFTING_CS alone 'for a normal user', although there is no
real dependency.
Is a 'select' then still a good option, since it feels like repeating
all dependencies from CAN_SOFTING in CAN_SOFTING_CS?
What about this?

---
It will present the Softing stuff in Kconfig as if CAN_SOFTING_CS really
depends on CAN_SOFTING, which is acceptible from a users perspective.
