And it's where it begins to be funny, as the LCD is precisely one aspect 
where we differentiate between sam9x75, sam9x72 and sam9x70...
So please Manikandan sort this out if difference between these chips 
will be better handled with different compatibility string, in 
particular about //, LVDS and MIPI-DSI variants!
