The drm_create_tv_properties() will create the TV mode property
unconditionally.
However, since we'll gradually phase it out, let's register it only if we
have a list passed as an argument. This will make the transition easier.

The TV mode property has been around for a while now to select and get the
current TV mode output on an analog TV connector.
Despite that property name being generic, its content isn't and has been
driver-specific which makes it hard to build any generic behaviour on top
of it, both in kernel and
As the number of kunit tests in KMS grows further, we start to have
multiple test suites that, for example, need to register a mock DRM
driver to interact with the KMS function they are supposed to test.
Let's add a file meant to provide those kind of helpers to avoid
duplication.

drm_mode_create_tv_properties(), among other things, will create the

However, that property is getting deprecated, so let's rename that

Hi,
Here's a series aiming at improving the command line named modes support,
and more importantly how we deal with all the analog TV variants.
The named modes support were initially introduced to allow to specify the
analog TV mode to be used.
However, this was causing multiple issues:

Hi Dave, Daniel,
Not sure if there is time for one more pull during the merge window, but
in case there is here it is. Only one which affects platforms outside
force_probe and that is the fix for DPT PTE corruption after resume. The
rest are all DG2 specific.
