The expected way of doing this is to describe whatever was attached via DT when it's attached - the device is what has the compatible, not some connector in the middle of the connection. The way you've got things set up if the device has a driver then they won't be able to instantiate the driver. [unhandled content-type:application/pgp-signature] | |
