No, it's a binding document for all of the ux500 driver and CODEC 
blocks. Do you really want me to split it all up? I think the only 
component which could be sanely split-out is the ab8500-codec, which 
could (should?) live in [1].

These properties are relevant for some, but not all of the components 
above, hence why the are listed at 'optional properties'.
