I see the problem has been addressed, so JFYI: a reverse selection doesn't resolve "depends on". It's a known shortcoming. That is, a selected item can select further others, but cannot depend on others.
The item will still be selected regardless of its dependencies, but Kconfig will print a warning if one or more of the dependencies are not met along with the dependency chain that causes the warning. So you'll have a clue why things go wrong.
