2025-05-02drm/msm/dpu: allow sharing SSPP between planesDmitry Baryshkov
Since SmartDMA planes provide two rectangles, it is possible to use them to drive two different DRM planes, first plane getting the rect_0, another one using rect_1 of the same SSPP. The sharing algorithm is pretty simple, it requires that each of the planes can be driven by the single rectangle and only consecutive planes are considered.

2025-05-02drm/msm/mdp4: switch LVDS to use drm_bridge/_connectorDmitry Baryshkov
LVDS support in MDP4 driver makes use of drm_connector directly. However LCDC encoder and LVDS connector are wrappers around drm_panel. Switch them to use drm_panel_bridge/drm_bridge_connector. This allows using standard interface for the drm_panel and also inserting additional bridges between encoder and panel.

2025-03-25drm/display: dp: change drm_dp_dpcd_read_link_status() return valueDmitry Baryshkov
drm_dp_dpcd_read_link_status() follows the "return error code or number of bytes read" protocol, with the code returning less bytes than requested in case of some errors. However most of the drivers interpreted that as "return error code in case of any error". Switch drm_dp_dpcd_read_link_status() to drm_dp_dpcd_read_data() and make it follow that protocol too.

2025-03-20drm/bridge: Add encoder parameter to drm_bridge_funcs.attachMaxime Ripard
The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

2025-03-05drm/msm/dpu: handle perf mode in _dpu_core_perf_crtc_update_bus()Dmitry Baryshkov
Move perf mode handling for the bandwidth to _dpu_core_perf_crtc_update_bus() rather than overriding per-CRTC data and then aggregating known values. Note, this changes the fix_core_ab_vote. Previously it would be multiplied per the CRTC number, now it will be used directly for interconnect voting. This better reflects user requirements in the case of different resolutions being set on different CRTCs: instead of using the same bandwidth for each CRTC (which is incorrect) user can now calculate overall bandwidth required by all outputs and use that value. Note #2: this also disables threshold checks for user-entered bandwidth values. First of all, it doesn't make sense to fail atomic commits because of the debugfs input. Compositors have no way to correlate failing commits with debugfs settings. Second, it makes sense to allow users to go beyond these values and check whether this makes any difference or fixes the issue.
