Makes me think.

I am asking about an example of this particular usage in the root node in device tree sources or bindings. You are asking about handling of the device tree root node in the barebox device/driver model. I don't see how that addresses my question. >> I'd rather not litter core code with an if-clause that evaluates to >> true only once, > > How many ifs are added in this patch and how many ifs will by added by > your suggestion?

My technical opinion is that the helper is wrongly used. >> of_device_make_bus_id is taken from Linux and does per comment: >> >> This routine will first try using the translated bus address to >> derive a unique name.

It's ultimately Sascha's choice what to merge. To me this is poor code, check my previous arguments.
