Porting AOSP to Allwinner Sunxi platform

With our recent efforts to get upstream Linux Kernel support for Allwinner Sunxi A133 and A523 platforms, this also includes the Display Engine. Although the whole upstream effort relies on reverse engineering the vendor blobs, we have managed to get the end-to-end display pipeline working with GPU and got LVDS and MIPI working. In some cases, we are able to get 2 parallel displays working.

Allwinner ships the most affordable SoCs / silicons for gaming consoles and handheld devices including tablets, all running vendor-provided Android. All of the devices come with closed source and proprietary blobs from Imagination Technologies, ARM Mali, and CedarX for the media pipelines.

This talk walks through our adventurous journey in building AOSP with upstream Linux Kernel 7.1 without any vendor-provided components to run an end-to-end display pipeline. We started our tinkering with Android 16 and easily moved to 17 (only released 6 days ago - relative to the date of this submission).

1. One doesn't need to get locked in with vendor-provided Android
2. How to reverse engineer all the needed components to get an end-to-end working AOSP
3. How the community can lead the way to try this for the A733 or any upcoming silicons from Allwinner, or any SoC vendor for that matter
