Modern SoCs often integrate multiple display controllers to support advanced use-cases such as multi-display setups, content mirroring, or screen extension. These controllers typically support heterogeneous interfaces like DSI, HDMI, OLDI, or (e)DP to accommodate a wide range of panels and bridge devices. Taking TI’s AM62P SoC as an example-which includes two display controllers, a GPU, and multiple interfaces such as DSI, DPI/HDMI, and OLDI-this talk will cover the design considerations involved in enabling Linux DRM driver support for such systems. It will explore two key approaches for supporting multiple controllers: integrating both under a single DRM card versus exposing them as 2x separate DRM cards, along with their pros and cons. The talk will also highlight the architectural changes made to support dual OLDI bridges multiplexed between controllers, allowing either configurations–dual-link (from a single controller) or 2x single-link (from separate controllers). Finally, it will discuss the challenges with DSI bridge integration, particularly around crtc-encoder-bridge operation sequences, and how bridge APIs can be used to support custom sequences for bridge operations.
