Looks good to me except I think the reset won't do anything currently
with ti-sysc.c unless you specfify also "ti,hwmods" for the module?

Can you please check? It might be worth adding the reset function to
ti-sysc.c for non "ti,hwmods" case and that just might remove the
need for any hwmod code for this module.

Regards,

Tony
