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

Subject: [PATCH] dt-bindings: pwm: mediatek: Remove gratuitous compatible
string for MT7629
The MT7629 is, in fact, not compatible with the MT7622 because the
former has a single PWM channel while the former has 6. Remove the
gratuitous compatible string for MT7629.
