   Wow, incredible coincidence that I was just adding a PR for lvgl.
   
   Regarding this change: this is not the way to do it since you are calling OS interfaces directly. In fact, I was also about to make a PR for a LCD character driver I wrote sometime ago and never upstreamed. It is exactly for this reason: it offers userspace interface to deal with LCDs. It also avoids the need for the framebuffer -> LCD driver which is quite inefficient in memory and communication.
