Hi Tony,
Seems something went wrong with your series. The introductory email can be
found only in linux-arm-kernel list but nowhere else and I can not find
the fifth patch at all.

Formal notes to this patch.
- Documentation/binding patches should go first in your series.
- Subject line should be: "dt-bindings: mfd: ..."
- Try to avoid the words [documentation, device tree, bindings] in subject.

See this patch [1] from Rob and add him to the recipients for v2.

Best regards,
Michal
