Arrgghh!  Okay, I guess knowing the name of the OF EDID block is not going
to be easy!

My tree has both "DFP,EDID", and "LCD,DFP" so my code only looks for:


I will add "EDID1" also (and "EDID2") just to make sure nothing breaks
along the way.

Ben is correct here, perhaps we should do our own I2C to grab our own EDID
block directly from the monitor and not play the "what name did OF give
it" game.

I have not looked at the I2C code to see how complex it is.  Does anyone
have any working code or sample code I can look at?
