--- Comment #99 from Jani Nikula <jani.nikula at intel.com> ---
The VBT blocks for the two panels are identical. Are the specs for the two
panels identical?

The VBT contains lots of configuration for the panel DPHY, initialization and
enable/disable sequences. Are the requirements for the two panels identical?

Has the VBT DSI configuration been tailored for the platform, board and panels?
The sequences contain GPIO toggles and DSI DCS commands. Any generic VBT will
not work.

What is the origin of the VBT configuration? Did someone provide it to you or
did you use the BMP tool to adjust and generate it?
