Looking at the DTS description for this downstream we see that snoc and snoc_mm share the same address space, the same clocks, indeed the only hint at all in qcom documentation these to are separate in anyway is boxes drawn on a diagram. snoc_mm is in fact simply two higher performance points for multimedia devices tacked onto the msm8916 snoc which was reused for msm8936/msm8939. The various client IP blocks make requests to vote for either X0 or GPLL0 clock rates with the multi-media votes indicating a higher operating point. We don't need to model snoc and snoc_mm separately since the datasheet for this part shows snoc_mm is not a separate device. Breaking up snoc into two pieces is a mistake that was made downstream which we carried over into upstream.

The difference can be captured with - A new clock - Performance points/clock settings in the relevant multi-media devices. Fix the above bug by representing snoc_mm as two new clocks to the existing snoc, not a separate interconnect bus.
