You pointed to a whole directory of bindings, based on the context below I assume you are talking about this: Documentation/devicetree/bindings/input/hid-over-i2c.yaml > > In this case, what can we do? hid-over-i2c dt-binding([1]) covers > information enough for our device to be used under I2C interface. > Therefore, the difference is seemingly going to be at "description". > Do we just provide a yaml file containing only the some of the > headers, such as id, schema, tiltle, and description items to submit > our dt-binding? If your controller is fully covered by hid-over-i2c.yaml binding then I think you just need to add a new compatible to it. We already have "wacom,w9013" there. Otherwise follow examples such as: Documentation/devicetree/bindings/input/elan,ekth6915.yaml Documentation/devicetree/bindings/input/goodix,gt7375p.yaml that are also hid-over-i2c devices but require special power up/down handling.
