I note that the driver attempts to probe with DT, yet there is no DT
binding in this patch, nor has the devicetree mailing list been placed
on Cc.

A DT binding document is mandatory for anything probing via DT.

Please write one, and submit it (as its own patch) with the next version
of this series as per
Documentation/devicetree/bindings/submitting-patches.txt.

Thanks,
Mark.
