No, definitely not two drivers for lp8788 hardware. If that does not yet exist... you want to create glue layer to be able to use LED as a display backlight. (It may already exist, no idea). =2E.. Actually or maybe a LED trigger. Just set LED's trigger to "this is display backlight". Other solutions are acceptable, but not two hardware drivers.
