29	  This module adds support for wireless adapters based on
30	  Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
31	  of chipsets. For a specific list of supported external
32	  cards, laptops that already ship with these cards and
33	  APs that come with these cards refer to ath9k wiki
34	  products page:
35
36	  http://wireless.kernel.org/en/users/Drivers/ath9k/products
37
38	  If you choose to build a module, it'll be called ath9k.
39
40config ATH9K_PCI
41	bool "Atheros ath9k PCI/PCIe bus support"
42	default y
43	depends on ATH9K && PCI
44	---help---
45	  This option enables the PCI bus support in ath9k.
46
47	  Say Y, if you have a compatible PCI/PCIe wireless card.
48
49config ATH9K_AHB
50	bool "Atheros ath9k AHB bus support"
51	depends on ATH9K
52	default n
53	---help---
54	  This option enables the AHB bus support in ath9k.
55
56	  Say Y, if you have a SoC with a compatible built-in
57	  wireless MAC. Say N if unsure.
58
59config ATH9K_DEBUGFS

61	depends on ATH9K && DEBUG_FS
62	select MAC80211_DEBUGFS
63	select ATH9K_COMMON_DEBUG

65	  Say Y, if you need access to ath9k's statistics for
66	  interrupts, rate control, etc.
67
68	  Also required for changing debug message flags at run time and for
69	  TX99.
70
71config ATH9K_STATION_STATISTICS
72	bool "Detailed station statistics"
73	depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS
74	select MAC80211_DEBUGFS

78
79config ATH9K_TX99
80	bool "Atheros ath9k TX99 testing support"
81	depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
82	default n
83	---help---
84	  Say N. This should only be enabled on systems undergoing
85	  certification testing and evaluation in a controlled environment.
86	  Enabling this will only enable TX99 support, all other modes of
87	  operation will be disabled.
88
89	  TX99 support enables Specific Absorption Rate (SAR) testing.
90	  SAR is the unit of measurement for the amount of radio frequency(RF)
91	  absorbed by the body when using a wireless device. The RF exposure
92	  limits used are expressed in the terms of SAR, which is a measure
93	  of the electric and magnetic field strength and power density for
94	  transmitters operating at frequencies from 300 kHz to 100 GHz.
95	  Regulatory bodies around the world require that wireless device
96	  be evaluated to meet the RF exposure limits set forth in the
97	  governmental SAR regulations.
98
99config ATH9K_DFS_CERTIFIED
100	bool "Atheros DFS support for certified platforms"
101	depends on ATH9K && CFG80211_CERTIFICATION_ONUS
102	default n
103	---help---
104	  This option enables DFS support for initiating radiation on
105	  ath9k. There is no way to dynamically detect if a card was DFS
106	  certified and as such this is left as a build time option. This
107	  option should only be enabled by system integrators that can
108	  guarantee that all the platforms that their kernel will run on
109	  have obtained appropriate regulatory body certification for a
110	  respective Atheros card by using ath9k on the target shipping
111	  platforms.
112
113	  This is currently only a placeholder for future DFS support,
114	  as DFS support requires more components that still need to be
115	  developed. At this point enabling this option won't do anything
116	  except increase code size.
117
118config ATH9K_DYNACK
119	bool "Atheros ath9k ACK timeout estimation algorithm"
120	depends on ATH9K
121	default n
122	---help---
123	  This option enables ath9k dynamic ACK timeout estimation algorithm
124	  based on ACK frame RX timestamp, TX frame timestamp and frame
125	  duration
126
127config ATH9K_WOW
128	bool "Wake on Wireless LAN support (EXPERIMENTAL)"
129	depends on ATH9K && PM
130	default n
131	---help---
132	  This option enables Wake on Wireless LAN support for certain cards.
133	  Currently, AR9462 is supported.
134
135config ATH9K_RFKILL
136	bool "Atheros ath9k rfkill support" if EXPERT
137	depends on ATH9K
138	depends on RFKILL=y || RFKILL=ATH9K
139	default y
140	help
141	  Say Y to have ath9k poll the RF-Kill GPIO every couple of
142	  seconds. Turn off to save power, but enable it if you have
143	  a platform that can toggle the RF-Kill GPIO.
144
145config ATH9K_CHANNEL_CONTEXT
146       bool "Channel Context support"
147       depends on ATH9K
148       default n
149       ---help---
150         This option enables channel context support in ath9k, which is needed
151	 for multi-channel concurrency. Enable this if P2P PowerSave support
152	 is required.
153
154config ATH9K_PCOEM
155	bool "Atheros ath9k support for PC OEM cards" if EXPERT

177	depends on ATH9K_HTC && DEBUG_FS
178	select ATH9K_COMMON_DEBUG
179	---help---
180	  Say Y, if you need access to ath9k_htc's statistics.
181	  As well as access to the FFT/spectral data.
182
183config ATH9K_HWRNG
184	bool "Random number generator support"
185	depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K)
186	default n
187	---help---
188	  This option incorporates the ADC register output as a source of
189	  randomness into Linux entropy pool (/dev/urandom and /dev/random)
190
191	  Say Y, feeds the entropy directly from the WiFi driver to the input
192	  pool.
