From ec66abb42d78c09c5a887e446f3d49c1af3560a0 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 13 Jun 2024 20:05:04 +0300 Subject: [PATCH] dt-bindings: display/msm/dsi: allow specifying TE source Command mode panels provide TE signal back to the DSI host to signal that the frame display has completed and update of the image will not cause tearing. Usually it is connected to the first GPIO with the mdp_vsync function, which is the default. In such case the property can be skipped.
