With that I don't think there's anything left from this series that you need. Let me know if that's not true.

("[v10,12/12] arm: dts: mediatek: add mt7629 pwm support") But, due to we use comaptible string separately for every SoC now, The comaptible string in dt-bindings should be "mediatek,mt7629-pwm". I think we should use "[v10,11/12] dt-bindings: pwm: update bindings for MT7629" to replace commit 1c00ad6ebf36aa3b0fa598a48b8ae59782be4121, Or maybe we need a little modification like this ? diff --git a/Documentation/devicetree/bindings/pwm/pwm-mediatek.txt ... - - "mediatek,mt7629-pwm", "mediatek,mt7622-pwm": found on mt7629 SoC. + - "mediatek,mt7629-pwm": found on mt7629 SoC. Thanks, Regards, Sam

Good catch, I must've taken this from the wrong version of the patch. How about the attached patch?
