From 1f7226a5e52cb8b90771cefc29077f9ce13a3c90 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Wed, 9 Aug 2023 14:15:58 +0530 Subject: [PATCH] arm64: dts: ti: k3-am625-beagleplay: Add HDMI support The DSS outputs DPI signals via its second video port (VP2). The DPI output from DSS is 24 bits (RGB888) and is forwarded to an HDMI transmitter (ITE-IT66121) on the BeaglePlay platform. For audio output, BeaglePlay uses mcasp1. Add pinmux info for DSS DPI signals. Further, add support for HDMI audio and video output.
