Why is this "ti,"?  For EDID, isn't the I2C device actually on the
monitor itself, and DVI cable just connects to the I2C bus?

Yes, in fact I didn't know what to put here, since I do not know what 
kind of eeprom the monitor will use.

And then I realized that the i2c driver is using the compatible name 
without the prefix, so any prefix can be used there...
OK, that's maybe not a very valid reason... but I did not find any 
better prefix at that time:-)

The reason I ask is that I'm trying to do the same thing for a PowerPC
board.  I need to defined an EDID I2C node.

Well, this seems to be generic i2c eeprom, so maybe a "ddc," prefix or 
"edid," will be a little bit better.

If later, we want to access that node from the display driver, we can 
just add a phandle to the node's label: "edid-eeprom: eeprom@50:"
