cd2c548652 ath5k: Move mac80211 functions into new file
Move mac80211 functions into new file mac80211-ops.c to have a better
separation and to make base.c smaller.

a0b907ee2a ath5k: Add AHB bus support.
AHB specific functions are now in ahb.c file. AHB bus is
compiled in when CONFIG_ATHEROS_AR231X is set in kernel.
All other platforms will use PCI bus.

40ca22eafe ath5k: add sysfs files for ANI parameters
/sys/class/ieee80211/phy0/device/ani/ani_mode
/sys/class/ieee80211/phy0/device/ani/noise_immunity_level
/sys/class/ieee80211/phy0/device/ani/spur_level
/sys/class/ieee80211/phy0/device/ani/firstep_level
/sys/class/ieee80211/phy0/device/ani/ofdm_weak_signal_detection
/sys/class/ieee80211/phy0/device/ani/cck_weak_signal_detection
/sys/class/ieee80211/phy0/device/ani/noise_immunity_level_max
/sys/class/ieee80211/phy0/device/ani/spur_level_max
/sys/class/ieee80211/phy0/device/ani/firstep_level_max

sysfs has a lot of symlinks, so you can find the files also in other locations,
like (by PCI ID) /sys/devices/pci0000:00/0000:00:11.0/ani and others.

2111ac0d88 ath5k: Adaptive Noise Immunity (ANI) Implementation
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked
at both ath9k and HAL sources (they are nearly the same), and even though i
have implemented some things differently, the basic algorithm is practically
the same, for now. I hope that this can serve as a clean start to improve the
algorithm later.

This also adds a possibility to manually control ANI settings, right now only
thru a debugfs file:
  * set lowest sensitivity (=highest noise immunity):
	echo sens-low > /sys/kernel/debug/ath5k/phy0/ani
  * set highest sensitivity (=lowest noise immunity):
	echo sens-high > /sys/kernel/debug/ath5k/phy0/ani
  * automatically control immunity (default):
	echo ani-on > /sys/kernel/debug/ath5k/phy0/ani
  * to see the parameters in use and watch them change:
	cat /sys/kernel/debug/ath5k/phy0/ani

Manually setting sensitivity will turn the automatic control off. You can also
control each of the five immunity parameters (noise immunity, spur immunity,
firstep, ofdm weak signal detection, cck weak signal detection) manually thru
the debugfs file.

This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band.

a6ae0716e5 ath5k: minor rfkill cleanup
Always enable rfkill since the ifdefs in the code is not really worth
the Kconfig option.  Also fix a few code style things, and remove the
usage of the ah_gpio[] array so we can remove it later.

e6a3b61681 ath5k: added cfg80211 based rfkill support
This patch introduces initial rfkill support for the ath5k driver
based on rfkill support in the cfg80211 framework.
All rfkill related code is separated into newly created rfkill.c.

Changes to existing code are minimal:

* added a new data structure ath5k_rfkill to the ath5k_softc structure
* inserted calls to HW rfkill init/deinit routines
* ath5k_intr() has been extended to handle AR5K_INT_GPIO interrupts
