From bac441710306a84c52f0f9a561aa9839b91caa14 Mon Sep 17 00:00:00 2001 From: Garrett Giordano Date: Mon, 4 Dec 2023 14:28:10 -0800 Subject: [PATCH] arm64: dts: ti: k3-am625-phyboard-lyra-rdk: 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 (SIL9022) on the board. Add pinmux for DSS DPI output and HDMI Interrupt. Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector on the phyBOARD-Lyra. Additionally, connect the output of DSS (VP2) with input of the HDMI TX, and the output of HDMI TX to the input of the HDMI connector.
