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