Subject: [PATCH v3 0/4] DVFS support for dpu and dsi

Changes in v3
- Added dev_pm_opp_put_clkname() in the error path

Changes in v2
- Patch 2: Dropped dsi_link_clk_set_rate_6g_v2 and dsi_link_clk_disable_6g_v2 as suggested by Matthias

These patches add DVFS support for DPU and DSI.

These patches have no other dependency. Patch 1 and 2 will need to be merged in
via the MSM DRM tree.

DT patches will need to land via the msm tree.

Rajendra Nayak (4):
  drm/msm/dpu: Use OPP API to set clk/perf state
  drm/msm: dsi: Use OPP API to set clk/perf state
  arm64: dts: sdm845: Add DSI and MDP OPP tables and power-domains
  arm64: dts: sc7180: Add DSI and MDP OPP tables and power-domains
