Should invoke tmc_init() in an ealier phase so it can prepare device class prior to the TMC devices registration? In other words, I think here should be:

subsys_initcall(tmc_init);

Your suggestion is very good. I will revise it according to your suggestion;

As I clarified for Mathieu's concerning in another reply, please ignore this comment.

Thanks, Leo
