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
