From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Very similar to the mpu6050 binding. Only unusual element is the i2c-gate section. Example tweaked a little to include a real device behind the gate. As Rob Herring suggested, dropped use of explicit i2c-gate yaml binding in favour of just using the i2c-controller.yaml binding directly.
