I believe AR5212 is a "version" and AR5213 is a "revision", so AR5212
can refer to AR5213 is some cases.  If you don't see the difference for
the registers you care about, perhaps there is no difference.

In the meantime, Sam Leffler opened its HAL, which also supports AR5416
(that's a "version") and should be more up-to-date.  You can check it
out by running

svn co svn://svn.freebsd.org/base/projects/ath_hal

I don't think there is any document describing differences between
chipsets.
