From: Dasnavis Sabiya Date: Thu, 19 Oct 2023 05:40:22 +0000 (+0530) Subject: arm64: dts: ti: k3-am69-sk: Add DP and HDMI support X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6f8605fd7d1160ab82b0fffb650180393c85c6fe;p=linux.git arm64: dts: ti: k3-am69-sk: Add DP and HDMI support AM69 starter kit features an HDMI port and an eDP port. Add assigned clocks for DSS, DT node for DisplayPort PHY, pinmux for HDMI hotplug and power down, mcu_i2c1 and dss_vout for HDMI. Also enable Serdes4 settings for DP display. Add the endpoint nodes to describe connection from: DSS => MHDP => DisplayPort connector DSS => TI TFP410 DPI-to-DVI Bridge => HDMI connector Signed-off-by: Dasnavis Sabiya [j-choudhary@ti.com: Fix dvi-bridge, dss, mhdp and serdes-refclk] Signed-off-by: Jayesh Choudhary Reviewed-by: Aradhya Bhatia Reviewed-by: Roger Quadros Link: https://lore.kernel.org/r/20231019054022.175163-6-j-choudhary@ti.com Signed-off-by: Vignesh Raghavendra --- diff --git a/arch/arm64/boot/dts/ti/k3-am69-sk.dts b/arch/arm64/boot/dts/ti/k3-am69-sk.dts index bc1d21ff6d033..9868c7049bfb9 100644 --- a/arch/arm64/boot/dts/ti/k3-am69-sk.dts +++ b/arch/arm64/boot/dts/ti/k3-am69-sk.dts @@ -251,6 +251,76 @@ states = <1800000 0x0>, <3300000 0x1>;
