DFS region support was added upstream via 8b60b07805

mcgrof at ergon ~/linux (git::master)$ git describe --contains 8b60b07805
v3.3-rc1~182^2~44^2~384

Now, that doesn't mean a driver will have DFS support of course. I'm
not going to treasure hunt that for you.

There's an issue Krishna reported about internal db now parsing the
new db.txt format properly after the antenna gain removal but a patch
is supposed to be on the way.  You don't seem to be using that though
so you may want to debug things a bit further.
