HDMI Output cannnot work in AGX Orin based CustomBoard 35.3.1

Hi,

The only check items for Orin HDMI are

  1. Pinmux
  2. DCB in dtb file needs to be correct. hotplug properties need to be added.
  3. Full flash instead of partial update.

And the only method to check this is xorg.0.log and xrandr result. Dmesg won’t show and /sys/kernel/debug/gpio won’t show anything either because the hotplug is handled by DCE R5 core. Not CCPLEX.
