OdroidN2/N2+ HDMI Green Line

Hi,

Writing to report an old issue about a green line on the left side of the
screen with some files hoping that it helps troubleshoot the cause. The 
issue
happens when connecting the HDMI cable directly to the hdmi input port 
of the
display, when using an HDMI to VGA converter and connecting it to the 
display
VGA input port the issue doesn't happen.

In this message I attach the output of "cat 
/sys/kernel/debug/dri/*/state" for
both hdmi and vga, also both edid files when connected to hdmi and vga. The
files were retrieved using kernel 5.18rc4 and happens on mainline uboot,
the tow-boot distribution or upstream uboot.
