I need to know the output in dmesg of the chipset MAC/PHY revisions.

Eventually, yes. As I said before, I have a local tree with
functioning, basic 11n HT/20 support. The driver needs further
attention before we can enable HT modes and have the chipsets have
even a remote hope of being stable and useful enough.

There's also quite a bit missing from my "basic 11n HT/20 support"
which doesn't even remotely work - eg legacy protection modes, making
sure HT/40 channel protection works, broken A-MPDU support (which
shouldn't be broken, that's another problem to fix) and rate control
module stuff. It was just enough for me to verify that actual TX/RX of
MCS rates worked (and it did, well enough.)

If someone can help me source an AR9285 NIC then I can also work on
that. Right now however, I'm just going to concentrate on the AR9160
and AR9220/AR9280 (same chipset, one being PCI and the other being
PCIe.)

As for turbo mode (and half/XR modes) and FF support - in ath9k, those
are all "deprecated". If you have access to older chips (so
AR5212/AR5213 and earlier) and would like to help debug this then
please pipe up.
