I agree, I think the has been going really well and we are just fighting
over a few details here. I was giving you all a hard time about the PCIe
driver, but that was actually less about the binding than about the
question whether to emulate P2P bridges or not. I still don't think
it's a good solution, but that is because of the hardware shortcomings
and all the alternatives are worse.

In case of the MBUS driver, I don't think it's a hard problem at all
(compared to the complexity of the PCIe driver and binding), we just
have to agree to do the right thing here.
