The reason for adding these new bindings is to enable the use of the driver on my machine. Without the compatible string, it would not be possible to use the driver. Currently, the driver initializes the device with defaults, which is good enough for my application. Also, as you previously pointed out, it uses the optional 'fan-supply' which will be included in the next patch revision. I hope this clarifies my reasoning.

Your entire explanation about compatible and driver is not related to the comment you received: bindings should be complete. You argue that bindings do not have to be complete, because of something with driver. This is not related. Bindings are not for driver.

However, the existence of a property in the bindings description does not have to be reflected in the driver. FWIW, you _could_ have added the device to the list of trivial devices.
