2009-04-22atheros: introduce ath module containing common ath5k/ath9k/ar9170 codeBob Copeland
This change creates a new module, ath.ko, which includes code that can be shared between ath5k, ath9k and ar9170. For now, extract most of the ath9k regulatory code so it can also be used in ath5k.

2009-04-22ath9k: pass regd structure directly to regulatory functionsBob Copeland
All regulatory information is encapsulated by the ath9k_regulatory struct, so we can now change all the callers to take that directly instead of struct ath_hw. This in turn will enable us to move the regulatory functions to common code also used by ath5k, since both can use this regulatory struct.

2009-01-29ath9k: simplify regulatory codeLuis R. Rodriguez
Now that cfg80211 has its own regulatory infrastructure we can condense ath9k's regulatory code considerably. We only keep data we need to provide our own regulatory_hint(), reg_notifier() and information necessary for calibration. Atheros hardware supports 12 world regulatory domains, since these are custom we apply them through the the new wiphy_apply_custom_regulatory(). Although we have 12 we can consolidate these into 5 structures based on frequency and apply a different set of flags that differentiate them on a case by case basis through the reg_notifier(). If CRDA is not found our own custom world regulatory domain is applied, this is identical to cfg80211's except we enable passive scan on most frequencies. Signed-off-by: Luis R.
