If we want to have vblank on both pipelines at the same time, we need to call drm_vblank_init with num_crtcs = 2. Instead, since the crtc init calls correctly set mode_config.num_crtc, we can move the drm_vblank_init call to after the crtc init code is called, which is the component bind part. Then we can just pass mode_config.num_crtc in.

The TCON has a mux to select the source of the data to display. This mux includes selecting the display backends. On the A31, which has two display pipelines, this mux can let the TCON select either backend as its data source. Although the muxing can be changed on the fly, DRM needs to be able to group a bunch of layers such that they get switched to another crtc together. This is because the display backend does the layer compositing, while the TCON generates the display timings. This constraint is not supported by DRM. Here we simply pair up backends and TCONs with the same ID.

The device tree binding for sun4i-drm says: For all connections between components up to the TCONs in the display pipeline, when there are multiple components of the same type at the same depth, the local endpoint ID must be the same as the remote component's index. For example, if the remote endpoint is Frontend 1, then the local endpoint ID must be 1. We should be able to get the TCON's ID directly from any of the remote endpoints from its input port. With the ID, we can then go through the list of registered engines and find a matching one by ID. However the A31 device tree is incorrect. We assumed that there were no cross pipeline connections between the backends and TCONs. As a result, in all the endpoints between the backends and TCONs of the second display pipeline, the endpoint IDs were incorrectly set to 0, when in fact they should've been set to 1. To maintain compatibility with this incorrect device tree, we first check if the TCON's input port has 1 or many endpoints. If there are more than 1, then it is likely a fixed version, and we can proceed with the new method. If there is only 1 endpoint, then it is possibly an incorrect version, or it could be the SoC only has one pipeline. In either case we fall back to using the old method of traversing the input connections to find a matching engine, and then get its ID.

The patch b317fa3b ("drm/sun4i: tcon: Find matching display backend by device node matching") assumed a one-to-one mapping between TCONs and backends. This turned out wrong, as we found muxing controls in the TCON of the A31, and undocumented usage of the backend output selector of the A20. Make sun4i_tcon_find_engine() bail out if the current node has multiple input connections.

The encoder drivers use drm_of_find_possible_crtcs to get upstream crtcs from the device tree using of_graph. For the results to be correct, encoders must be probed/bound after _all_ crtcs have been created. The existing code uses a depth first recursive traversal of the of_graph, which means the encoders downstream of the TCON get add right after the first TCON. The second TCON or CRTC will never be properly associated with encoders connected to it. Other platforms, such as Rockchip, deal with this by probing all CRTCs first, then all subsequent components. This is easy to do since the CRTCs correspond to just one device node, and are the first nodes in the pipeline. However with Allwinner SoCs, the function of the CRTC is split between the display backend (DE 1.0) or mixer (DE 2.0), which does scan-out and compositing, and the TCON, which generates the display timing signals. Further complicating the process, there may be a Dynamic Range Controller between the backend and the TCON. Also, the backend is preceded by the frontend, with a Display Enhancement Unit possibly in between. In a dual display pipeline setup, both frontends can feed either backend, and both backends can feed either TCON. We want all components of the same type to be added before the next type in the pipeline. Fortunately, the pipelines are perfectly symmetric, i.e. components of the same type are at the same depth when counted from the frontend. The only exception is the third pipeline in the A80 SoC, which we do not support anyway. Hence we can use a breadth first search traversal order to add components. We do not need to check for duplicates. The component matching system handles this for us.

When binding the TCON, we were checking the reset control status and asserting reset if it wasn't in reset. The check failed to account for the reset control API returning error codes if the status callback was not implemented. Since we want the TCON to be reset in all cases, use reset_control_reset to force a reset instead.

By always keeping track of the last commit in plane_state, we know whether there is an active update on the plane or not. With that information we can reject the fast update, and force the slowpath to be used as was originally intended. We cannot use plane_state->crtc->state here, because this only mentions the most recent commit for the crtc, but not the planes that were part of it. We specifically care about what the last commit involving this plane is, which can only be tracked with a pointer in the plane state. Changes since v1: - Clean up the whole function here, instead of partially earlier. - Add mention in the commit message why we need commit in plane_state. - Swap plane->state in intel_legacy_cursor_update, instead of reassigning all variables. With this commit We know that the cursor is not part of any active commits so this hack can be removed.

Currently we neatly track the crtc state, but forget to look at plane/connector state. When doing a nonblocking modeset, immediately followed by a setprop before the modeset completes, the setprop will see the modesets new state as the old state and free it. This has to be solved by waiting for hw_done on the connector, even if it's not assigned to a crtc. When a connector is unbound we take the last crtc commit, and when it stays unbound we create a new fake crtc commit for that gets signaled on hw_done for all the planes/connectors. We wait for it the same way as we do for crtc's, which will make sure we never run into a use-after-free situation. Changes since v1: - Only create a single disable commit. (danvet) - Fix leak in intel_legacy_cursor_update. Changes since v2: - Make reference counting in drm_atomic_helper_setup_commit more obvious. (pinchartl) - Call cleanup_done for fake commit.

When commit synchronization through drm_crtc_commit was first introduced, we tried to solve the problem of the flip_done needing a reference count by blocking in cleanup_done. This has been changed by commit 24835e44 ("drm: reference count event->completion") which made the waits here no longer needed. However, even after this commit we still needed the wait because otherwise we cannot wait for the flip_done because this item might have been removed from the list.
