[PATCH v6] drm/msm/a6xx: Add support for an interconnect path

2019-01-18 Thread Jordan Crouse
Try to get the interconnect path for the GPU and vote for the maximum bandwidth to support all frequencies. This is needed for performance. Later we will want to scale the bandwidth based on the frequency to also optimize for power but that will require some device tree infrastructure that does not
