Thanks for the clarification! I assumed these were the same thing because the patches were posted just after we had talked about the other one. > Kenneth would better be able to clarify how dynamic the SLIMbus is. That would definitely be helpful. Also, I'd be very interested to hear what kind of device probing is available on slimbus. If Mark was right about devices being discoverable, we need don't need any board description (dts or hardcoded) but instead a way to match the devices to drivers based on their HW ID. Arnd
