+ driver
+
+The node for this driver must be a child node of a I2C controller, hence
+all mandatory properties for your controller must be specified. See directory:
+
+ Documentation/devicetree/bindings/i2c
+
+for more details.

+Required properties:
+ - compatible: Must be one of the following, depending on the
+ model:
