Subject: [PATCH v6 0/6] Add support for GPU DDR BW scaling

This series add support for GPU DDR bandwidth scaling and is based on the
bindings from Georgi [1]. This is mostly a rebase of Sharat's patches [2] on the
tip of msm-next branch.

[2] https://patchwork.freedesktop.org/series/75291/

Changes from v5:
- Added "interconnect-names" property

Changes from v4:
- Squashed a patch to another one to fix Jonathan's comment
- Add back the pm_runtime_get_if_in_use() check

Changes from v3:
- Rebased on top of Jonathan's patch which adds support for changing gpu freq
through hfi on newer targets
- As suggested by Rob, left the icc_path intact for pre-a6xx GPUs

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
