[PATCH v3 0/6] Add support for GPU DDR BW scaling

[Sharat Masetty]

This is a respin of [1]. Incorported review feedback and fixed issues observed
during testing. Picked up the Georgi's series from opp/linux-next [2], and this
series is also dependent on a helper function needed to set and clear ddr
bandwidth vote [3]. Patch number 4 in the series adds support for SDM845 as well
but its not tested yet(WIP), but the SC7180 patches are well tested now.

Sharat Masetty (6):
  dt-bindings: drm/msm/gpu: Document gpu opp table
  drm: msm: a6xx: send opp instead of a frequency
  drm: msm: a6xx: use dev_pm_opp_set_bw to scale DDR
  arm64: dts: qcom: SDM845: Enable GPU DDR bw scaling
  arm64: dts: qcom: sc7180: Add interconnects property for GPU
  arm64: dts: qcom: sc7180: Add opp-peak-kBps to GPU opp
