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