No, it doesn't.
The next version should probably say something like "Add compatible
string for the Qualcomm WCN3998 Bluetooth controller.
[Harish] -- From new patch onwards will add all patch
version changes and add proper description.
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?).
[Harish] -- I think in DT we need to have small case like wcn, i think
that is the reason it started using in code, comments and dt
documentation.

changes in v3:
- updated to latest code base.
This comment is useless, please describe what changed wrt the previous
version.
[Harish] -- added details in v2, and v3 uploaded just to rebase on tip
of bluetooth-next
for better understanding of code in review. From new patch onwards will
add all patch
version changes and add proper description.

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).
[Harish] -- Will check the DT properties, documentation and update
accordingly in new patch.
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.
[Harish] -- for now we want to add WCN3998 support only, What i mean to
say in my earlier
explanation that. WCN3990 is base variant and on top of that we have
variants like WCN3990,
WCN3998 and WCN3998-0,WCN3998-1 like that..
So I think wcn399x would make sense for this series.
Thanks
Matthias
Thanks,
