In general it looks fine to me. What really worries me is the calls like

of_foo -> fwnode_bar -> of_baz.

As I have commented in one patch the idea of fwnode APIs is to have a
common ground for all resource providers. So, at the end it shouldn't
be a chain of calls like above mentioned. Either fix the name (so, the
first one will be in fwnode or device namespace) or fix the API that
it will be fwnode/device API.
