Hi Jose,

All the above issues are getting resolved after updating the TCON FW on the
panel.

Attaching the patches which i have created for updating TCON FW on the AUO
Panel. 

Also, listing down the steps for updating the TCON FW on the panel:

Step 1. Build the kernel using the attached patches

Step 2: After that, copy the attached files in the /tmp folder of the DUT

Step 3: Make sure output of below cmd is 'N'
cat /sys/kernel/debug/dri/dpcd_read_once
N

Step 4: Run below command:
echo "Y" > /sys/kernel/debug/dri/dpcd_read_once

Step 5: Run below command
localhost /tmp # python ./tcon_fw_updater.py -v update fw_filename

Step 6: echo "N" > /sys/kernel/debug/dri/dpcd_read_once
