From 5875428ac6c7d687f9a51aef7c8665310f06be64 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Wed, 17 Dec 2025 11:19:04 +0100 Subject: [PATCH] arm64: dts: mediatek: mt8188: Add DPI1, HDMI, HDMI PHY/DDC nodes Add all of the nodes that are required to enable HDMI output, including ones describing the HDMI PHY, Controller and DDC, and the Digital Parallel Interface instance that is internally connected to the HDMI Controller. All of the added nodes are disabled by default as usage is board dependent.
