[PATCH 3/6] dt-bindings: display: mediatek: Allow trigger-sources on relevant HW

AngeloGioacchino Del Regno angelogioacchino.delregno at collabora.com
Wed Jul 1 05:20:40 PDT 2026 

Most of the MediaTek Display Controller hardware sub-IPs need a
specific (and reserved to them) MuteX trigger.

Since now MuteX is a trigger source, allow specifying trigger
sources in all of the display IPs that support one.
