Hi Bjorn,

The rc5 is out there and we are approaching rc6. 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!

Shawn
