Hi Dmitry, I believe Krzysztof is waiting for Ack on the binding before merging this patch (and the rest), but unfortunately it was not sent to the DT mailing list for review.

Indeed I am still waiting for Rob's and Thierry's acks for this and the following patches. It has been just a week so I'll give it few more days. Best regards, Krzysztof

Rob doesn't review patches which aren't sent to the DT ML, which isn't cc'ed in v10 by accident. I'll make v11.

Document opp-supported-hw property, which is not strictly necessary to have on Tegra20, but it's very convenient to have because all other SoC core devices will use hardware versioning, and thus, it's good to maintain the consistency.
