Bluetooth modules in the same system.

This module adds support for wireless adapters based on
Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
of chipsets. For a specific list of supported external
cards, laptops that already ship with these cards and
APs that come with these cards refer to ath9k wiki
products page:
https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products
If you choose to build a module, it'll be called ath9k.
config ATH9K_PCI
bool "Atheros ath9k PCI/PCIe bus support"
default y
depends on ATH9K && PCI
help
This option enables the PCI bus support in ath9k.
Say Y, if you have a compatible PCI/PCIe wireless card.
config ATH9K_AHB
bool "Atheros ath9k AHB bus support"
depends on ATH9K
default n
help
This option enables the AHB bus support in ath9k.
Say Y, if you have a SoC with a compatible built-in
wireless MAC. Say N if unsure.
config ATH9K_DEBUGFS

depends on ATH9K && DEBUG_FS
select MAC80211_DEBUGFS

help
Say Y, if you need access to ath9k's statistics for
interrupts, rate control, etc.
Also required for changing debug message flags at run time and for
TX99.
config ATH9K_STATION_STATISTICS

This option enables detailed statistics for association stations.
config ATH9K_TX99
bool "Atheros ath9k TX99 testing support"
depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
default n
help
Say N. This should only be enabled on systems undergoing
certification testing and evaluation in a controlled environment.
Enabling this will only enable TX99 support, all other modes of
operation will be disabled.
TX99 support enables Specific Absorption Rate (SAR) testing.
SAR is the unit of measurement for the amount of radio frequency(RF)
absorbed by the body when using a wireless device. The RF exposure
limits used are expressed in the terms of SAR, which is a measure
of the electric and magnetic field strength and power density for
transmitters operating at frequencies from 300 kHz to 100 GHz.
Regulatory bodies around the world require that wireless device
be evaluated to meet the RF exposure limits set forth in the
governmental SAR regulations.
config ATH9K_DFS_CERTIFIED
bool "Atheros DFS support for certified platforms"
depends on ATH9K && CFG80211_CERTIFICATION_ONUS
default n
help
This option enables DFS support for initiating radiation on
ath9k. There is no way to dynamically detect if a card was DFS
certified and as such this is left as a build time option. This
option should only be enabled by system integrators that can
guarantee that all the platforms that their kernel will run on
have obtained appropriate regulatory body certification for a
respective Atheros card by using ath9k on the target shipping
platforms.
This is currently only a placeholder for future DFS support,
as DFS support requires more components that still need to be
developed. At this point enabling this option won't do anything
except increase code size.
config ATH9K_DYNACK
bool "Atheros ath9k ACK timeout estimation algorithm"
depends on ATH9K
default n
help
This option enables ath9k dynamic ACK timeout estimation algorithm
based on ACK frame RX timestamp, TX frame timestamp and frame
duration
config ATH9K_WOW
bool "Wake on Wireless LAN support (EXPERIMENTAL)"
depends on ATH9K && PM
default n
help
This option enables Wake on Wireless LAN support for certain cards.
Currently, AR9462 is supported.
config ATH9K_RFKILL
bool "Atheros ath9k rfkill support" if EXPERT
depends on ATH9K
depends on RFKILL=y || RFKILL=ATH9K
default y
help
Say Y to have ath9k poll the RF-Kill GPIO every couple of
seconds. Turn off to save power, but enable it if you have
a platform that can toggle the RF-Kill GPIO.
config ATH9K_CHANNEL_CONTEXT
bool "Channel Context support"
depends on ATH9K
default n
help
This option enables channel context support in ath9k, which is needed
for multi-channel concurrency. Enable this if P2P PowerSave support
is required.
config ATH9K_PCOEM

depends on ATH9K
default y
config ATH9K_PCI_NO_EEPROM
tristate "Atheros ath9k pci loader for EEPROM-less chips"
depends on ATH9K_PCI
default n
help
This separate driver provides a loader in order to support the
AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have
their initialization data (which contains the real PCI Device ID
that ath9k will need) stored together with the calibration data out
of reach for the ath9k chip.
These devices are usually various network appliances, routers or
access Points and such.
If unsure say N.

Support for Atheros HTC based cards.
Chipsets supported: AR9271
For more information:
https://wireless.wiki.kernel.org/en/users/Drivers/ath9k_htc
The built module will be ath9k_htc.
config ATH9K_HTC_DEBUGFS
bool "Atheros ath9k_htc debugging"

Say Y, if you need access to ath9k_htc's statistics.
As well as access to the FFT/spectral data.

depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K)
default n
help
This option incorporates the ADC register output as a source of
randomness into Linux entropy pool (/dev/urandom and /dev/random)
Say Y, feeds the entropy directly from the WiFi driver to the input
pool.
config ATH9K_COMMON_SPECTRAL
bool "Atheros ath9k/ath9k_htc spectral scan support"

help
Say Y to enable access to the FFT/spectral data via debugfs.
