[PATCH 6/6] arm64: dts: qcom: sm6125: Add missing MDSS core reset
From: Val Packett
Date: Mon Feb 16 2026 - 18:40:43 EST
To make sure the display subsystem starts in a predictable state, we
need to reset it. On closely related SoC (sm6115) this has caused
DSI displays to not work.
Wire up the reset to fix.
