Add support for describing the media bus format in the panel configuration and expose that to userspace. Since both supported formats (RGB565 and RGB666) are using 6 bits per color also hardcode that information. Reviewed-by:

Sebastian Reichel authored
Avoid hard-coding the default_mode and supply it from match data. One additional layer of abstraction has been introduced, which will be needed for specifying other panel information (e.g. bus flags) in the next steps. Reviewed-by:

As we gain more tests, boilerplate to allocate an atomic state and free it starts to be there more and more as well. In order to reduce the allocation boilerplate, we can create a helper to create that atomic state, and call an action when the test is done. This will also clean up the exit path. Reviewed-by:

As we get more and more tests, the locking context initialisation creates more and more boilerplate, both at creation and destruction. Let's create a helper that will allocate, initialise a context, and register kunit actions to clean up once the test is done. Reviewed-by:
