Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

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. This patch was created using: rg -l drm_atomic_state | \ xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g' mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c Acked-by: Simona Vetter Acked-by: Thomas Zimmermann Acked-by: Jani Nikula Reviewed-by: Luca Ceresoli Tested-by: Luca Ceresoli Signed-off-by: Maxime Ripard Signed-off-by: Dave Airlie Link: https://patch.msgid.link/20260427-drm-drm-atomic-update-v4-1-c0e713bfdf25@kernel.org

drm/mxsfb/lcdif: use DRM_BRIDGE_ATTACH_NO_CONNECTOR and the bridge-connector

2026-04-14T11:53:36+00:00

Convert this driver to DRM_BRIDGE_ATTACH_NO_CONNECTOR and to the drm_bridge_connector framework which is the current DRM bridge best practice. Based on the in-tree dts[i] files this introduces no regression. Based on the kernel doc of drm_bridge_connector.c: * To make use of this helper, all bridges in the chain shall report bridge * operation flags (&drm_bridge->ops) and bridge output type * (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach * flag (none of the bridges shall create a DRM connector directly). and each of the 3 LCDIF blocks in the i.MX8MP, all of them comply with the above requirement: * For the LCDIF3, the pipeline is: LCDIF3 -> fsl,imx8mp-hdmi-pvi -> fsl,imx8mp-hdmi-tx -> HDMI connector And the involved bridges are: * fsl,imx8mp-hdmi-pvi has ops = 0 (it doesn't set it) because it implements none the optional features mentioned by those flags, and it honors the DRM_BRIDGE_ATTACH_NO_CONNECTOR by propagating it * fsl,imx8mp-hdmi-tx is implemented based on dw-hdmi, which sets ops as appropriate and also propagates the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag * display-connector (enabled via the DT overlay if needed) sets ops and makes DRM_BRIDGE_ATTACH_NO_CONNECTOR mandatory * The LCDIF2 involves the panel-bridge, display-connector and lvds-decoder (even though only the pane-bridge is currently supported), and all these three also set ops as needed and propagate DRM_BRIDGE_ATTACH_NO_CONNECTOR or make it mandatory. * The LCDIF1 is used with the adv7511, tc358767 and the panel bridge drivers which also comply with the requirements.

drm/mxsfb/lcdif: move iteration-specific variables declaration inside loop in lcdif_attach_bridge

2026-04-14T11:52:31+00:00

The bridge and ret variables are per-iteration variables, whose values don't have to be carried to the next iteration or be used after the loop end. Move their declaration inside the loop scope as a cleanup and to make code clearer.
