[PATCH] arm64: dts: qcom: sdm845-oneplus: add panel rails to simplefb

From: Sam Day via B4 Relay

Date: Tue Jun 16 2026 - 01:27:40 EST


From: Sam Day <me@xxxxxxxxxxx>

These regulators are marked regulator-boot-on, but that doesn't
guarantee they'll stay alive as long as the simplefb does. Adding the
explicit supplies ensures that booting with MDSS disabled doesn't
switch the panel off 30 seconds after boot.
