[PATCH v5 2/2] arm64: dts: qcom: glymur-crd: Enable eDP display support

From: Abel Vesa

Date: Thu Mar 19 2026 - 09:13:31 EST


From: Abel Vesa <abel.vesa@xxxxxxxxxx>

Enable the MDSS (Mobile Display SubSystem), the third DisplayPort
controller, and its PHY to drive the onboard eDP panel on the Glymur
CRD platform. Also describe the regulator supplying panel power.
