Each SLIMBus Component contains one Interface Device. Which is 
responsible for Monitoring and reporting the status of component, Data 
line to Data pin connection setup for SLIMBus streaming. Interface 
device is enumerated just like any other slim device.

We already have exactly same bindings for WCD9335 in upstream at:

"SLIMBus Interface Device" itself is documented in SLIMBus Specification.

If I remember it correctly You suggested me to move to "slim-ifc-dev" 
as this is part of SLIMBus Specification.
