Hmm, yes, perhaps that would work for these DPI panels.

The reason I originally put the backlight driver inside the panel driver
is that there are many panels for which the backlight is a part of the
panel, in the sense that the backlight is controlled by sending messages
to the panel. For these the backlight needs to be somewhat integrated
into the panel driver.
