I've been worried about DT overhead adding to boot time for a while. And IMHO probe deferral is just about the lamest way to solve boot order dependencies I can imagine, from a computer science perspective.

It has a bogosort kind of elegance. :) Also this might be a silly question (I haven't been following this issue for very long), but as the only place that can really know what devices depend on each other, in a generic kernel, is the DT (or whatever abstraction) will we not eventually need to solve this issue there? Could we just add a "depends-on = <&phandle>;" to nodes when we know they are needed for our board? -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
