Browse source

[WHAT]
Add KUnit tests for amdgpu_dm_connector_init_helper() covering the
common connector defaults and attached properties, the HDMI,
DisplayPort, DVI-D, VGA, eDP and unhandled connector types, an MST
branch connector that skips the root-only properties, the content
protection property and the default HPD debounce delay.
