[PATCH 4/4] arm64: dts: qcom: glymur-crd: Enable HDMI output via PS195
From: Nabige Aala
Date: Thu Nov 12 2026 - 06:05:13 EST
From: Mahadevan P <mahadevan.p@xxxxxxxxxxxxxxxx>
Enable the PS195 HDMI path on Glymur CoB/SiP, Mahua and Kalambo CRDs
through their shared glymur-crd.dtsi.
Describe the bridge, connector, supplies and four-lane DP2 connection
through the USB2 QMP combo PHY. Add the GPIO126 HPD state to glymur.dtsi.
