[PATCH v1 1/2] dt-bindings: display: panel: Add LG LP156WF1

From: Vitor Soares

Date: Fri May 29 2026 - 07:07:15 EST


From: Vitor Soares <vitor.soares@xxxxxxxxxxx>

Add device tree binding for the LG LP156WF1 15.6" Full-HD (1920x1080)
dual-channel LVDS panel.

Also add lg,lp156wf1 to the panel-lvds.yaml exclusion list to prevent
false schema matches.
