Let me clarify a little more. ath9k_htc is a module which will use ath_htc and ath_hif_usb. ath9k_htc delcares hardware support for the 802.11n Atheros 9k family for devices which use HTC. The ar9271 usb device gets probed by ath_hif_usb. ath9k_htc is being designed as the mac80211 driver for ar9271 but it may be possible to just share the same ath9k_htc for all SoftMAC Atheros 11n HTC devices. Now, ar6k is FullMAC so an ath9k_htc per se is not needed but I'd expect you'd just need to implement a ar6k.c which uses cfg80211 and adds support for the ar6k hw famiy. You'd need to implement an ath_hif_sdio.c to handle the SDIO transport and this would be the module probing the ar6k devices over sdio. Now, sure, I don't expect any PCI/USB ar6k devices but still, this is the architectural approach I'd like to see.
