Message

Rajendra Nayak July 9, 2020, 11:04 a.m. UTC

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.
