Yes, I think the driver should work once dtsi updated.
("[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,
