[PATCH 0/3] Remove brownout risks from DPU
From: Konrad Dybcio
Date: Tue Jul 28 2026 - 09:26:07 EST
Things generally run better when plugged in. That also happens to hold
for clocks. To ensure that is the case, remove calls that drop the
performance state votes while the clocks are still running.
This helps Glymur devices not crash upon resume when a display
(incl. the internal one) is plugged in.
The DSI patch is compile-tested only.
