Sorry Vlad I don't see much basis litigating this further. I've been very clear, I think we should have standalone CSIPHYs, there's no reason to bury them inside of the CAMSS block - see CCI. There's a clear way to do endpoints established from sensor to consumer, there's no reason to give that data to the above CSIPHY driver, it has no "use case" for it. Its unfortunate we've done parallel work but, I'd ask you at this point to rebase your multiple sensor work on the proposed CSIPHY series here and for drivers/phy. I very much look forward to and value your contribution to enabling multiple sensors on the CSIPHY predicated on that rebase. --- bod
