I think this should also mention the default value.

BTW, somehow I'd think this should be handled in a more generic place,
like in the drm module. But that's another issue.

Default value would be useful here as well. And I think the description
should be a little more verbose here, as I don't immediately see how
"scale" is related to tv-out. Does it mean the amount of overscan? Or
does it change default scaling method?
