drm/vc4: vec: Add the margin properties to the connector

2024-06-20T08:02:41+00:00

All the handling for the properties was present, but they
were never attached to the connector to allow userspace
to change them.

Add them to the connector.

drm/vc4: Add monochrome mode to the VEC.

2024-06-20T08:02:33+00:00

The VEC supports not producing colour bursts for monochrome output.
It also has an option for disabling the chroma input to remove
chroma from the signal.

Now that there is a DRM_MODE_TV_MODE_MONOCHROME defined, plumb
this in.

drm/vc4: tests: Convert to plane creation helper

2024-05-28T08:24:42+00:00

Now that we have a plane create helper for kunit mocked drivers, let's
convert to it in vc4.

drm/vc4: tests: Remove vc4_dummy_plane structure

2024-05-28T08:24:42+00:00

The vc4_dummy_plane structure was introduced as a mean to add
mock-specific fields.

However, we never really used it and it's still strictly equivalent to
vc4_plane (which is in the same situation vs drm_plane), so we can
simply remove the vc4_dummy_plane structure and make the mock code
cleaner.

drm/vc4: hdmi: Switch to HDMI connector

2024-05-28T08:24:41+00:00

The new HDMI connector infrastructure allows us to remove a lot of
boilerplate, so let's switch to it.

Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"

2024-05-02T15:58:23+00:00

This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in.  Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

drm/print: drop include debugfs.h and include where needed

2024-04-25T14:05:48+00:00

Surprisingly many places depend on debugfs.h to be included via
drm_print.h. Fix them.

v3: Also fix armada, ite-it6505, imagination, msm, sti, vc4, and xe

v2: Also fix ivpu and vmwgfx
