It seems quite unlikely we will get these dependencies land on linux-next in time, even though these bindings already got enough Acks/Reviews. I understand this is summer and maintainers may be on holidays. But I don't really want to see the whole series miss the 7.3 merge window due to the dependencies that are only required by patch 5/6 (nord-ride.dts). So may I ask you to apply the series excluding patch 5/6, if the rest of the series looks good to you? Let me know if you want a resend. Thank you!
