From: Dasnavis Sabiya <sabiya.d@xxxxxx>

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

Although DT binding doc for ti,tfp410 says encoder
a name starting with bridge maybe more appropriate.

Will keep it as bridge-dvi.

Will edit the node names in suggested in 3/5 and 4/5 as well.
I will address the new-line comments too.

Thanks
