    Pull i2c component probing support from Wolfram Sang:
     "Add OF component probing.
    
      Some devices are designed and manufactured with some components having
      multiple drop-in replacement options. These components are often
      connected to the mainboard via ribbon cables, having the same signals
      and pin assignments across all options. These may include the display
      panel and touchscreen on laptops and tablets, and the trackpad on
      laptops. Sometimes which component option is used in a particular
      device can be detected by some firmware provided identifier, other
      times that information is not available, and the kernel has to try to
      probe each device.
    
      Instead of a delicate dance between drivers and device tree quirks,
      this change introduces a simple I2C component probe function. For a
      given class of devices on the same I2C bus, it will go through all of
      them, doing a simple I2C read transfer and see which one of them
      responds. It will then enable the device that responds"
