? Sorry, but each time Pavel jumps in, he just copies half of a statement and
any reply gets misunderstood.

I did not even mention platform_device, still you disagree to device tree for the
*slave driver*?

Sorry, but I don't see how Rob's approach makes it simpler to write a device driver
than our original proposal, which btw is also sort of a bus and I see only some implementation
differences.

Except that IMHO Rob's approach lacks functions we need (which maybe can added).
