[PATCH v4 2/2] arm64: dts: qcom: glymur-crd: Enable eDP display support
From: Abel Vesa
Date: Mon Mar 09 2026 - 11:02:10 EST
From: Abel Vesa <abel.vesa@xxxxxxxxxx>
Enable the MDSS (Mobile Display SubSystem) along with the 3rd
DisplayPort controller and its PHY in order to bring support
for the panel on Glymur CRD platform. Also describe the voltage
regulator needed by the eDP panel.
