+DT folks
Please add them in future versions (script/scripts/get_maintainer.pl
<patches> should have listed them)

No, it doesn't.
The next version should probably say something like "Add compatible
string for the Qualcomm WCN3998 Bluetooth controller.
Is there any particular reason why QCA drivers folks use 'wcn' instead
of 'WCN'? The QCA documentations calls it WCN399x, so I'd suggest to
consistently use the uppercase name in comments and documentation (and
log messages?).

This comment is useless, please describe what changed wrt the previous
version.

I think the example isn't really needed since it's essentially the
same as the one for 'qcom,wcn3990-bt'.
But the important part is missing: add the new compatible string under
´Required properties´. You also want to update the documentation that
mentiones 'qcom,wcn3990-bt' to 'qcom,wcn399x-bt' (assuming for now
that other possible WCN399x chips would be similar).
You mentioned in an earlier version of the series that there are
multiple WCN3998 variants with different requirements for
voltage/current. This seems to suggests that multiple compatible
strings are needed to distinguish between them.
Thanks
