The QCA6390 package contains discreet modules for WLAN and Bluetooth. They
are powered by the Power Management Unit (PMU) that takes inputs from the
host and provides LDO outputs. This document describes this module.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Mark,

This is quite vague, could you elaborate? I have no idea what is wrong
with this patch.

The subject line does not look like the subject line for a regulator
patch rendering it almost invisible in my inbox.  As you will see if you
follow the above suggestion and look at other commits to the same area
you should see that subject lines should start regulator:.

Use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

This matches our internal discussions and how we see the QCA6390 power
handling based on datasheet.

Yes, I always do. And for Documentation/devicetree/bindings/regulator/
the subjects are split 50:50 between "dt-bindings: regulator: ..." and
"regulator: dt-bindings: ...". For Documentation/devicetree/bindings/
it's overwhelmingly "dt-bindings: <subsystem>: ...". It's the first
time someone wants me to send a DT bindings patch without
"dt-bindings" coming first in the subject.

I mean: I can do it alright but it's not stated anywhere explicitly.

No, there are only ~54 "dt + regulator" ones and around 400 starting
with "regulator" (Mark removes first prefix if it is not regulator:). So
50 to 400 is not 50:50.

Well, practice was kind of known and obvious, but it is also stated:
