drm/imx: parallel-display: Switch to atomic_create_state

2026-06-22T09:24:41Z

The drm_bridge_funcs.atomic_reset callback and its drm_atomic_helper_bridge_reset() helper are deprecated. Switch to the atomic_create_state callback and its drm_atomic_helper_bridge_create_state() counterpart.

drm: Rename struct drm_atomic_state to drm_atomic_commit

2026-05-04T04:05:04Z

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.

drm/bridge: Move legacy bridge driver out of imx directory for multi-platform use

2026-04-09T12:10:21Z

As suggested by Dmitry, the DRM legacy bridge driver can be pulled out of imx/ subdir for multi-platform use. The driver is also renamed to make it more generic and suitable for platforms other than i.MX.

drm/imx: ipuv3-plane: support underlay plane

2026-03-13T15:27:06Z

The IPUv3 overlay plane may be placed over or under the primary plane. Set the zpos of the primary to an immutable position of 1 to have the possibility to place the other plane underneath it. Set the zpos of other planes (the overlay plane) to a mutable value between 0 (the lowest possible value of a zpos) and directly above the primary plane with the latter being the default.

The overlay plane may be placed over or under the primary plane. Using zpos to determine, if the plane is the primary or overlay plane is not valid anymore. Use the plane type for determining the name of the plane in the error message.
