drm: Add Allwinner A10 Display Engine support The Allwinner A10 and subsequent SoCs share the same display pipeline, with variations in the number of controllers (1 or 2), or the presence or not of some output (HDMI, TV, VGA) or not. Add a driver with a limited set of features for now, and we will hopefully support all of them eventually Reviewed-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

sun4i_hdmi: add CEC support Add HDMI CEC support to the Allwinner A10 SoC. This SoC uses a poor-man's CEC implementation by polling the CEC pin. It is using the CEC_PIN core implementation for such devices to do the heavy lifting. It just provides the callbacks to read/drive the CEC pin.

drm/sun4i: Add Allwinner A31 MIPI-DSI controller support 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.
