The MIPI Display Serial Interface (MIPI DSI) is a versatile, high-speed interface for a variety of embedded solutions and it is the most common and widely used display interface.

Many users are moving to open source solutions and it becomes a daunting task for them to bring their LCD panels into working and usable state because of lack of technical documentation and guidelines for their vendor specific panels along with associated DSI controllers. So, this talk will address those issues and challenges which are observed while working on Allwinner MIPI DSI controller with variety of associated LCD panels, bridges by validating these interfaces via ARM Mali GPU.

This talk starts with a brief overview of Linux DRM subsystem with bounded display controller interfaces like HDMI, RGB, LVDS and DSI and then the talk will add more details about Linux MIPI DSI controller, DPHY, DSI panel, DSI bridge interfaces drivers along with how these display drivers interact with GPU drivers.
