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/bridge: inno-hdmi: Switch to atomic_create_state

2026-06-22T09:24:26+00:00

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

2026-05-04T04:05:04+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

drm/display: hdmi: Use drm_output_color_format instead of hdmi_colorspace

2026-03-24T12:54:35+00:00

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.

During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.

However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state
to facilitate the current effort to provide a global output format
selection mechanism.

drm/bridge: refactor HDMI InfoFrame callbacks

2026-01-19T11:11:46+00:00

Having only a single set of callbacks, hdmi_clear_infoframe and
hdmi_write_infoframe, bridge drivers don't have an easy way to signal to
the DRM framework, which InfoFrames are actually supported by the
hardware and by the driver and which are not. Also, it makes it
extremely easy for HDMI bridge drivers to skip implementing the
seemingly required InfoFrames (e.g. HDMI VSI). Last, but not least,
those callbacks take a single 'type' parameter, which makes it
impossible to implement support for multiple VSIs (which will be
required once we start working on HDMI Forum VSI).

Split the callbacks into a per-InfoFrame-kind pairs, letting the bridge
drivers actually signal supported features. The implementation follows
the overall drm_bridge design, where the bridge has a single
drm_bridge_funcs implementation and signals, which functions are to be
called using the drm_bridge->ops flags.

The AVI and HDMI VSI are assumed to be required for a normal HDMI
operation (with the drivers getting a drm_warn_once() stub
implementation if one is missing). The Audio InfoFrame is handled by the
existing DRM_BRIDGE_OP_HDMI_AUDIO, while the SPD and HDR DRM InfoFrames
got new drm_bridge_ops values.

drm/rockchip: inno-hdmi: Convert to drm bridge

Convert it to drm bridge driver, it will be convenient for us to
migrate the connector part to the display driver later.
