I'm just Googling, but see
https://bitbucket.org/freebsd/freebsd-head/src/3ce34df9366f/sys/dev/ath/ath_hal/ar5212/
They look closely related. I started by Googling "AR5212 datasheet" and
ended up with 2 copies of a 1-page advertising PDF. The 5112 and 5212
seem to be parts of the AR5002x. The Atheros stuff seems to have one
number like AR5002* referrring to a package of a "radio on a chip" plus a
processor. The radios are different, the processors are different, and
the different AR5002* packages are different as a result. 3 numbers for
each combination.
Nothing like an official API yet though.

The odd thing is that this card works in a machine with FreeBSD 7.1 and that
identifies the chip as "Atheros 5212". So which chip number is right?
Could the problem have to do with misidentifying the chip? dmesg, pcidump
and the driver think it's an AR5311.
I've got 4.7 running on my laptop with an internal mini-pci card which has
either a 5212 or 5213A depending on where in the dmesg output you look, and
that works fine. pcidump calls that a 5212. So much for accuracy.
Back to the PCI-mounted one: A FreeBSD 7.0 live CD I've got calls it an
AR5211 with a HAL status of 13. OpenBSD installs 4.7 & 4.4 call it an
AR5311 with a HAL status 22. OpenBSD 4.1 install calls it a 5211, 4.0 & 4.2
don't find it (floppy install image). Debian Linux 5.03 calls it an ath5k
and says it fails the POST.
It's good you've mentioned it. I tried to work with a laptop using
Atheros chipset for wireless. OpenBSD dmesg shows Atheros AR5424 and
another number like AR5xxx I can't remember, but I can't find this
model on Qualcomm Atheros site. Windows XP shows Atheros AR5700
series. Which is what ? Maybe someone who got it right can give us a
clue.
Thanks
