Re: [PATCH] of: support an enumerated-bus compatible value

One would think that, but the of_address handling code actually treats
empty ranges the same as missing ranges, in violation of the spec,
and as a workaround to deal with some powermac machines that required
this.

I'd rather fix the code to deal with this correctly.

OK, so what is correctly then?

Adding an explicit enumerated-bus compatible value/node-type/binding
seems like "correctly" to me, but it seemed like others didn't agree.

I'm talking about the issue that you cannot currently have a bus
without a "ranges" property and #size-cells=<0> and expect Linux
to turn the devices on it into platform devices, because the
of_translate_address function fails on this.
