The chip AR9170 is getting on a bit. But ok.

A (compiled) firmware is available from:
http://wireless.kernel.org/en/users/Drivers/carl9170

and the firmware source from:
https://github.com/chunkeey/carl9170fw

The driver and firmware are GPLv2 code.

Well, the original vendor firmware:
http://linuxwireless.org/en/users/Drivers/ar9170.fw
and the original vendor driver:
[ The most up-to-date version is available from the
kernel git. Just revert "staging: remove the Atheros otus vendor driver"
cff55f50b882b197a52c4cf0108a43c615d1fdba ] 

For more [HW design docs, register file, etc...] you need to talk to
Qualcomm Atheros. But if there's an open issue/specific question I
would be glad to help as well [or forward the request].
