Exactly, the values are part of downstream dtsi[0]. The docs for this
property are:
- qcom,msm-bus,vectors-KBps:
Arrays of unsigned integers representing:
* master-id
* slave-id
* arbitrated bandwidth in KBps
* instantaneous bandwidth in KBps
The first two paths downstream are consolidated into one here, the third
downstream is the second one here.

Hope that clears it up!
