You need to CC' the devicetree maintainers:
Mark Rutland <mark.rutland@xxxxxxx>
Rob Herring <robh+dt@xxxxxxxxxx>
devicetree@xxxxxxxxxxxxxxx
for all patches which touch Documentation/devicetree/... .
Also, I know (from experience) that they would prefer it, if you put
the device tree binding patch at the top of the series (i.e. make it:
[PATCH 1/2] dt-bindings...). ;-)

Documentation/devicetree/bindings/vendor-prefixes.txt has an entry for
Qualcomm Atheros, Inc. => qca. I would use that instead, given that this
is a new binding, so there's '"no"' legacy code to worry about.
