Hi all, I am working on U-Boot mainline (targeting the v2026.04 cycle) and I plan to implement splash screen support for sunxi platforms (t113s) via MIPI DSI.
Currently, I have mainline booting and loading the kernel on my hardware, but I lack display output in the bootloader. My plan is to backport the sun6i-mipi-dsi and associated DPHY logic from Linux kernel v6.10. Given the shift toward OF_UPSTREAM in recent U-Boot releases, I intend to leverage the existing kernel Devicetree bindings as much as possible. Before I proceed further, I’d like to seek guidance to ensure I’m not heading in the wrong direction: 1. *Ongoing Work:* Is anyone else currently working on MIPI DSI for sunxi? I want to avoid duplicating efforts if there are existing WIP patches or branches. 2. *Driver Structure:* Does the community prefer a minimal "U-Boot-style" driver, or a more direct port of the Linux DRM bridge/host structure (similar to how some Rockchip DSI drivers were recently integrated)? Thanks and Best regards, Jian Zhang
