Thanks for your patch. It's indeed an improvement over the old code and I can
test it tomorrow when I've access to my machine with a max77802 PMIC.
However, I don't think this is the change that Mark asked. AFAIU what he wanted
is to fill the struct regulator_desc .of_match and .regulators_node fields so
the init_data is extracted by the core on regulator registration.
Look at commits a0c7b164 ("regulator: of: Provide simplified DT parsing method")
and 93a127b ("regulator: isl9305: Convert to new style DT parsing") to see what
I'm talking about.
Best regards,
Javier
