[RFC] More compatibles or more quirk properties

[Mitch Bradley]

> I'm running into a dilemma choosing between two approaches of defining device tree binding.  Let's say if we have several chips with a similar SoC block, but each of them have different quirks.  If I define different compatibles for each of the chips, the driver will have a longer match table and thus bloat the device matching process.  Or we can use a same compatible for all of them and  define properties for each of the quirks.  But it somewha
Properties to describe quirks precisely are definitely better.  In fact, 
that's fundamental principle - describe the situation, don't infer a 
bunch of details from a name.
