I keep forgetting to update my eDP spec 1.4 to this 1.4b...
Maybe the patch should then make this clear, by annotating it with /* eDP 1.4b */ That's missing, which isn't all that great really, since it makes specs hunts like yours necessary.
It's actually in eDP 1.4 spec, table 5-6 page 86
Please fix up before applying. -Daniel
