Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

You missed at least devicetree list (maybe more), so this won't be
tested by automated tooling. Performing review on untested code might be
a waste of time, thus I will skip this patch entirely till you follow
the process allowing the patch to be tested.

Please kindly resend and include all necessary To/Cc entries.

Best regards,
Krzysztof

The DT bindings have been fully reviewed and acked in the previous
versions, and haven't changed in v7. Do you still want to be CC'ed in
such cases ?

I don't have to (that's just a template message), but DT list must be.
People introduce some changes and some bugs after they got review, thus
every posting should be checked by the automation.

Best regards,
Krzysztof

+description:
+  The THP7312 is a standalone ISP controlled over i2c, and is capable of
+  various image processing and correction functions, including 3A control. It
+  can be connected to CMOS image sensors from various vendors, supporting both
+  MIPI CSI-2 and parallel interfaces. It can also output on either MIPI CSI-2
+  or parallel. The hardware is capable of transmitting and receiving MIPI
+  interlaved data strams with data types or multiple virtual channel
+  identifiers.
