Are you suggesting the one panel you mention is representative of the
real world?

Granted, the original aux backlight implementation supported a very
narrow selection of panels. I believe this is the very reason you are
working on this patch series.

But now you're suggesting another arbitrary narrow selection of panels
based on limited evidence.
