Except that this binding is missing 'additionalProperties: false' at this level. That should be fixed first. I would suggest you keep these here and make the if/then schema just not allow properties (e.g. "drive-strength-microamp: false"). > power-source: > description: I/O voltage in millivolt. > enum: [ 1800, 2500, 3300 ] > - slew-rate: true > gpio-hog: true > gpios: true > input-enable: true > -- > 2.39.2 >

LGTM, once you have taken Rob's comments into account. Gr{oetje,eeting}s, Geert
