You can accomplish this by having the demod create an i2c adapter instance, which generates i2c commands to the bridge. Then when instantiating the tuner subdev, pass a pointer to the demod's i2c adapter instead of the i2c adapter provided by the bridge. No changes required to the core framework. Devin -- Devin J.
