Hi, Here's a small patchset that I created while playing with PostmarketOS on my Samsung Galaxy S2. The first two patches update the LD9040 panel driver so that it looks much better, and supports setting the backlight. The third patch fixes the size of the panel in the Device Tree. The previous values were completely bogus and caused Phosh (PmOS' UI) to display tiny icons and text as it thought the DPI was much lower.
