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

This is a rework of my previous series [1], but this time based on the bindings
from Georgi [2] + a few fixes which look to be fixed in v8 of Georgi's series
[3]. The work is based on the chromeOS tip.

Sharat Masetty (5):
  arm64: dts: qcom: sc7180: Add interconnect bindings for GPU
  arm64: dts: qcom: sc7180: Add opp-peak-kBps to GPU opp
  drm: msm: a6xx: send opp instead of a frequency
  drm: msm: a6xx: use dev_pm_opp_set_bw to set DDR bandwidth
  dt-bindings: drm/msm/gpu: Document gpu opp table

Sibi Sankar (1):
  OPP: Add and export helper to set bandwidth
