drm: zynqmp_dp: switch to of_drm_get_bridge_by_endpoint()

2026-05-19T08:57:26+00:00

This driver calls drm_of_find_panel_or_bridge() with a NULL pointer in the @panel parameter, thus using a reduced feature set of that function. Replace this call with the simpler of_drm_get_bridge_by_endpoint(). Since of_drm_get_bridge_by_endpoint() increases the refcount of the returned bridge, ensure it is put on removal. To achieve this, instead of adding an explicit drm_bridge_put(), migrate to the bridge::next_bridge pointer which is automatically put when the bridge is eventually freed.

drm/xlnx/zynqmp-dpsub: Fix dependencies for COMPILE_TEST

2026-05-06T08:00:03+00:00

The zynqmp-dpsub driver does not have build time dependencies on the PHY or DMA drivers. These are runtime hardware restrictions. Make the two dependencies optional if COMPILE_TEST.

drm: xlnx: zynqmp: Use drm helpers when calculating buffer sizes

2026-05-05T11:04:29+00:00

Use drm helpers, drm_format_info_plane_width(), drm_format_info_plane_height() and drm_format_info_min_pitch() to calculate sizes for the DMA. This cleans up the code, but also makes it possible to support more complex formats (like P030, P230).

drm: Rename struct drm_atomic_state to drm_atomic_commit

2026-05-04T04:05:04+00:00

The KMS framework uses two slightly different definitions for the state concept. For a given object (plane, CRTC, encoder, etc., so drm_$OBJECT_state), the state is the entire state of that object. However, at the device level, drm_atomic_state refers to a state update for a limited number of objects. Thus, drm_atomic_state isn't the entire device state, but only the full state of some objects in that device. This has been an endless source of confusion and thus bugs. We can rename the drm_atomic_state structure to drm_atomic_commit to make it less confusing.
