Subject: [PATCH RESEND v11 5/5] arm64: dts: ti: k3-am69-sk: Add DP and HDMI support
From: Dasnavis Sabiya <sabiya.d@...com>
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
