drm/msm/hdmi: Use the common TMDS char rate constants in 8998 PHY

2026-05-21T09:45:53+00:00

Replace the driver local defines with the shared constants defined in the
 header for the minimum and maximum TMDS character rates.

drm/msm/hdmi: switch to of_drm_get_bridge_by_endpoint()

2026-05-19T08:57:25+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.

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/msm/hdmi: Drop redundant 'int' for longs

'long' type is already an integer, so 'int' is redundant.

2026-03-25T06:06:09+00:00

Linux coding style asks to use kernel types like u32 instead of uint32_t
and code already has it in other places, so unify the remaining pieces.
