- switch everything over to inline comments - add notes about locking, links to functions and other related stuff - also include a note about Ville's soon-to-be-merged drm_connector_for_each_possible_encoder(). Also check that all the hyperlinks in drm_connector.h work and fix them as needed. Reviewed-by:

Last bit the prevented us from starting to delete the drmP.h monster includes from source files! Also add kernel-doc while moving them. A nice consistent drm_dev_ prefix would be cute for these, but since they're used everywhere I've figured I'll leave this bikeshed aside for now. Reviewed-by:

AFBC is a proprietary lossless image compression protocol and format. It provides fine-grained random access and minimizes the amount of data transferred between IP blocks. AFBC has several features which may be supported and/or used, which are represented using bits in the modifier. Not all combinations are valid, and different devices or use-cases may support different combinations. Changes from v2:- - Added ack by Maarten Lankhorst Signed-off-by:

Everything (apart from the actual ->set_config() call) __drm_mode_set_config_internal() does is now useless on atomic drivers. So let's just skip all the foreplay. v2: Use drm_drv_uses_atomic_modeset() (Daniel) Signed-off-by:

All the plane->fb/old_fb/crtc dance of __setplane_internal() is pointless on atomic drivers. So let's just introduce a simpler version that skips all that. Ideally we could also skip the __setplane_check() as drm_atomic_plane_check() already checks for everything, but the legacy cursor/"async" .update_plane() tricks bypass that so we still need to call __setplane_check(). Toss in a FIXME to remind someone to clean this up later. v2: Use drm_drv_uses_atomic_modeset() (Daniel) Signed-off-by:

This adds support for the DisplayPort CEC-Tunneling-over-AUX feature that is part of the DisplayPort 1.3 standard. Unfortunately, not all DisplayPort/USB-C to HDMI adapters with a chip that has this capability actually hook up the CEC pin, so even though a CEC device is created, it may not actually work.

When commit af11942e ("drm/sun4i: tcon-top: Cleanup clock handling") was merged, the error handling path of the of_property_match_string was changed to take into account the fact that the returned value of that function wasn't an error pointer but an error code. Unfortunately, this introduced a warning since the now returned value is an integer, while the sun8i_tcon_top_register_gate function should return an error pointer. Fix that by calling ERR_PTR.

Initial implementation of DE2 planes only supported fixed zpos. Expand implementation with configurable zpos property. Implementation background: Channel in DE2 driver represents one DRM plane, whereas pipe is just mapped channel to known Z position. Pipe 0 will always be at the bottom, pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear on top. Before this commit, channel id was used for addressing channel related registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_) and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally, register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so on. Consequence of all that was fixed Z order of planes. With this commit, pipe registers are using zpos property as index and channel related registers still use channel id as index. Pipe mapping register is now set dynamically too and pipe enable register is rebuild every time to make sure only active pipes are enabled. Testing was done to confirm that there is no issues if bottom plane contains pixels with alpha value < 0xff and if it doesn't whole screen. Tested-by:

Having DRM_SUN4I built-in but DRM_SUN8I_MIXER as a loadable module results in a link error, as we try to access a symbol from the sun8i_tcon_top.ko module: ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun8i-drm-hdmi.ko] undefined! ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun4i-drm.ko] undefined! This solves the problem by adding a silent symbol for the tcon_top module, building it as a separate module in exactly the cases that we need it, but in a way that it is reachable by the other modules.

Currently, TCON supports 2 ways to match TCON with engine (mixer in this case). Old way is to just traverse of graph backwards and compare node pointer. New way is to match TCON and engine by their respective ids. All SoCs with DE2 enabled till now used the old way, which means mixer id was never used and thus never implemented. However, for R40, only the new way will be used. To prepare for that, implement mixer id fetching from DT. Reviewed-by:

Commit 894a677f ("drm/cma-helper: Use the generic fbdev emulation") broke almost all drivers that use the CMA helper. The reason is that drm_client_new() requires that the DRM device has been registered, but the drivers register fbdev before registering DRM. Remove the requirement that DRM should be registered when creating a new client.
