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
Copy and paste the wrong one.
0x2009 is actually in eDP 1.4 spec, Table 6-7: DPCD – Sink Device PSR Status Field page 124
Please fix up before applying.
