      1Qualcomm SLIMBus Non Generic Device (NGD) Controller binding
      2
      3SLIMBus NGD controller is a light-weight driver responsible for communicating
      4with SLIMBus slaves directly over the bus using messaging interface and
      5communicating with master component residing on ADSP for bandwidth and
      6data-channel management
      7
      8Please refer to slimbus/bus.txt for details of the common SLIMBus bindings.
