It might happen, that command when run on an older kernel, gives you outdated entries.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. Tools like b4 or scripts/get_maintainer.pl provide you proper list of people, so fix your workflow. Tools might also fail if you work on some ancient tree (don't, instead use mainline) or work on fork of kernel (don't, instead use mainline). Just use b4 and everything should be fine, although remember about `b4 prep --auto-to-cc` if you added new patches to the patchset. 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. Please kindly resend and include all necessary To/Cc entries. </form letter> > --- > .../devicetree/bindings/net/wireless/qca,ath9k.yaml | 12 ++++++++++++ > 1 file changed, 12 insertions(+) > > diff --git a/Documentation/devicetree/bindings/net/wireless/qca,ath9k.yaml b/Documentation/devicetree/bindings/net/wireless/qca,ath9k.yaml > index 0e5412cff2bc..5c293d558a94 100644 > --- a/Documentation/devicetree/bindings/net/wireless/qca,ath9k.yaml > +++ b/Documentation/devicetree/bindings/net/wireless/qca,ath9k.yaml > @@ -44,6 +44,16 @@ properties: > > ieee80211-freq-limit: true > > + qca,led-active-high: > + $ref: /schemas/types.yaml#/definitions/flag > + description: > + Indicates that the LED pin is active high instead of low Where is DTS user of it?

None at this time. There are only downstream users. This maps to the led_active_high in ath9k_platform_device , which gets removed in a subsequent commit. drivers/net/wireless/mediatek/mt76/mac80211.c uses led-sources as the name for the same purpose. Maybe rename? > > Best regards, > Krzysztof >

Maybe rename? Again, you add undocumented, unused compatibles along with unused properties. We don't care about downstream kernels. You need upstream users. Best regards, Krzysztof
