These structs are identical, use a single struct to represent private data for the DRM plane. This is a preparation for configuring layer routing from the CRTC (mixer) instead of current approach of setting up routing from individual layer's atomic_update callback.

These will be needed later on when we move layer configuration to crtc update. Signed-off-by: Ondrej Jirman <[email protected]> file: drm-sun4i-Add-more-parameters-to-sunxi_engine-commit-callback.patch
Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed. Signed-off-by: Ondrej Jirman <[email protected]> file: drm-sun4i-Fix-layer-zpos-change-atomic-modesetting.patch
Add support for gamma corretion to sun4i TCON driver. Its LUT has 256 entries and can be updated only when gamma correction is disabled. Signed-off-by: Vasily Khoruzhick <[email protected]> file: drm-sun4i-Implement-gamma-correction.patch

Добавил поддержку HDMI на основе патчей Armbian.
Патчи Armbian взяты за основу, так как в ядре mainline еще нет полной поддержки HDMI для нашего чипа (только DE33).
HDMI с данными патчами работает из коробки (консоль по HDMI запускается при загрузке), для поддержки Xorg нужно поставить соответствующие пакеты. После установки Xorg также работает с HDMI из коробки.
