As I said, I didn't have enough exposure to the ARM SoC so I can't answer that > If this binding is going to continue to be relevant to future DPAA > generations, I think we really ought to deal with the possibility that > there is more than one datapath instance I'm unsure how relevant this will be going forward. In LS2 B/QMan is abstracted/hidden away behind the MC (firmware). I wouldn't over-engineer this without a clear picture of what multiple data-paths per SoC even means at this point > by having phandles and/or a parent container to connect the related > components. Connecting the related components is beyond the scope of this binding. It will soon hit the e-mail list(s) as part of upstreaming the Ethernet driver Cheers, -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
