  "this component is primarily a part of the qualcom proprietary QPMDA
  subsystem, and is capable of operating independently from the
  CoreSight hardware trace generation system." -- From Mike

While he didn't explicitly ask to "change the compatible and hardware 
name", from his above remark, i think he doesn't consider this component 
to be part of the coresight subsystem as it can operate independently.

That's why, in the latest version of the binding, i've removed the 
coresight keyword from the compatible.
