From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> As Rob Herring suggested, this no long requires the explicit i2c-gate binding, but instead just used i2c-controller.yaml directly. 2 prior examples combinded into one as a single example can show all of the binding elements as long as the right part is selected.
