Background: Macbook air LP8550 backlight IC uses custom slope to adjust brightness smoothly. If you solder on LP8550 from mouser or random ebay seller, you will have default ladder-style brightness adjustment which does not look nice especially when it goes from 10% to 100% due to ambient light change. Turns out this is a simple parameter which could be flashed directly from Linux.
