drm/tests: Add tests for the new Monochrome value of tv_mode

2024-07-01T09:50:19+00:00

Adds test for the cmdline parser, connector property, and
drm_analog_tv_mode to ensure the behaviour of the new value is
correct.

drm/tests: modes: Remove call to drm_kunit_helper_free_device()

2023-07-31T12:19:57+00:00

Calling drm_kunit_helper_free_device() to clean up the resources
allocated by drm_kunit_helper_alloc_device() is now optional and not
needed in most cases.

Remove it.

drm/tests: helpers: Allow for a custom device struct to be allocated

2022-12-08T08:56:55+00:00

The current helper to allocate a DRM device doesn't allow for any
subclassing by drivers, which is going to be troublesome as we work on
getting some kunit testing on atomic modesetting code.

Let's use a similar pattern to the other allocation helpers by providing
the structure size and offset as arguments.

drm/tests: helpers: Create the device in another function

2022-12-08T08:56:55+00:00

We'll need in some tests to control when the device needs to be added
and removed, so let's split the device creation from the DRM device
creation function.

drm/tests: helpers: Remove the name parameter

2022-12-08T08:56:55+00:00

The device name isn't really useful, we can just define it instead of
exposing it in the API.

drm/tests: helpers: Rename the device init helper

2022-12-08T08:56:55+00:00

The name doesn't really fit the conventions for the other helpers in
DRM/KMS, so let's rename it to make it obvious that we allocate a new
DRM device.

drm/tests: helpers: Move the helper header to include/drm

2022-12-08T08:41:26+00:00

We'll need to use those helpers from drivers too, so let's move it to a
more visible location.

drm/modes: Add a function to generate analog display modes

2022-11-24T11:42:39+00:00

Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and
625-lines modes in their drivers.

Since those modes are fairly standard, and that we'll need to use them
in more places in the future, it makes sense to move their definition
into the core framework.

However, analog display usually have fairly loose timings requirements,
the only discrete parameters being the total number of lines and pixel
clock frequency. Thus, we created a function that will create a display
mode from the standard, the pixel frequency and the active area.
