commit cb80ff7184884dd861daa539e4bc4cdd66f3077e
Author: Michael Opdenacker <michael.opdenacker at free-electrons.com>
Date:   Wed Dec 7 22:58:08 2016 +0100

    Replace i2c dts example
    
    - There is an issue in the  sun7i-a20-bananapi.dts file used as example.
      There is no "compatible" property for the axp209 node.  Other boards have one.
