Using MIPI DSI as Main Display Interface
Explore the intricacies of using MIPI Display Serial Interface (DSI) as the main display interface in embedded systems. Delve into the Verdin MIPI DSI Display Adapter system design and the Verdin DSI to LVDS Adapter. Gain insights into the Linux DSI subsystem and the Linux DRM stack DSI bridge chip integration, including potential pitfalls. Examine the DSI bridge chip ecosystem, supported bridge chips in mainline, and auto-detection of DSI adapters based on EEPROM contents. Learn about U-Boot's role in reading EEPROM contents, selecting applicable device tree overlays, and using FIT images for board-specific and display adapter-specific device trees. Discover device tree overlay pitfalls and witness a live demonstration of DSI auto-detection in this comprehensive conference talk.
