Documentation

This property defines how a non-native mode is upscaled to the native
mode of an LCD panel:

None:
	No upscaling happens, scaling is left to the panel. Not all
	drivers expose this mode.
Full:
	The output is upscaled to the full resolution of the panel,
	ignoring the aspect ratio.
Center:
	No upscaling happens, the output is centered within the native
	resolution the panel.
Full aspect:
	The output is upscaled to maximize either the width or height
	while retaining the aspect ratio.

This property should be set up by calling
drm_connector_attach_scaling_mode_property(). Note that drivers
can also expose this property to external outputs, in which case they
must support "None", which should be the default (since external screens
have a built-in scaler).
