[iMX8QM MEK CAR] Drive a custom resolution display through LVDS-HDMI port 1 (ldb2)

Dear Team,

Platform: iMX8QM MEK

Software: Android-11

 

I am driving 2 displays through LVDS-HDMI-0 (ldb1) and LVDS-HDMI-1 (ldb2).

Currently, I want to disable EDID modes of LVDS-HDMI-1 (ldb2) and set a custom resolution of 1920x550. Could you help me disable get_edid_modes and override using custom resolution.

 

  1. What are the changes that I need to do in DTS file?
  2. What are the changes that I need to do in gpu/drm/ driver codes?
  3. What are that changes that I need to do in BoardConfig.mk?

 

Best regards,

Jose1985
