Most of the Allwinner SoCs since the A31 share the same MIPI-DSI controller. While that controller is mostly undocumented, the code is out there and has been cleaned up in order to be integrated into DRM. However, there's still some dark areas that are a bit unclear about how the block exactly operates.
