Hi,
I would expect to make it also depend on device tree or architectures which support device tree. From what I remember, there are still architectures which have not yet been converted to devicetree. In those cases, it would be confusing and useless to build this module. Or am I missing something? I don't have any practical experience with devicetree, so far.
