Spectral scan support is currently the only user +of RELAY in ath9k, and it unconditionally reserves a relay channel. + +Having debugfs support in ath9k is often useful even on very small embedded +routers, where we'd rather like to avoid the code size and RAM usage of the +relay support. + +Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> +Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> +--- + drivers/net/wireless/ath/ath9k/Kconfig | 14 ++++++++++---- + drivers/net/wireless/ath/ath9k/Makefile | 4 ++-- + drivers/net/wireless/ath/ath9k/common-spectral.h | 4 ++-- + 3 files changed, 14 insertions(+), 8 deletions(-) + +--- a/drivers/net/wireless/ath/ath9k/Kconfig ++++ b/drivers/net/wireless/ath/ath9k/Kconfig +@@ -64,13 +64,12 @@ config ATH9K_DEBUGFS + depends on ATH9K && DEBUG_FS + select MAC80211_DEBUGFS + select ATH9K_COMMON_DEBUG +- depends on RELAY + ---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. +- As well as access to the FFT/spectral data and TX99. ++ Also required for changing debug message flags at run time and for ++ TX99. + + config ATH9K_STATION_STATISTICS + bool "Detailed station statistics" +@@ -181,7 +180,6 @@ config ATH9K_HTC_DEBUGFS + bool "Atheros ath9k_htc debugging" + depends on ATH9K_HTC && DEBUG_FS + select ATH9K_COMMON_DEBUG +- depends on RELAY + ---help--- + Say Y, if you need access to ath9k_htc's statistics. + As well as access to the FFT/spectral data. +@@ -197,3 +195,11 @@ config ATH9K_HWRNG + + 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" ++ depends on ATH9K_DEBUGFS || ATH9K_HTC_DEBUGFS ++ depends on RELAY ++ default n ++ ---help--- ++ Say Y to enable access to the FFT/spectral data via debugfs. +--- a/drivers/net/wireless/ath/ath9k/Makefile ++++ b/drivers/net/wireless/ath/ath9k/Makefile +@@ -61,8 +61,8 @@ ath9k_common-y:= common.o \ + common-init.o \ + common-beacon.o \ + +-ath9k_common-$(CPTCFG_ATH9K_COMMON_DEBUG) += common-debug.o \ +- common-spectral.o ++ath9k_common-$(CPTCFG_ATH9K_COMMON_DEBUG) += common-debug.o ++ath9k_common-$(CPTCFG_ATH9K_COMMON_SPECTRAL) += common-spectral.o + + ath9k_htc-y += htc_hst.o \ + hif_usb.o \ +--- a/drivers/net/wireless/ath/ath9k/common-spectral.h ++++ b/drivers/net/wireless/ath/ath9k/common-spectral.h +@@ -151,7 +151,7 @@ static inline u8 spectral_bitmap_weight( + return bins[0] & 0x3f; + } + +-#ifdef CPTCFG_ATH9K_COMMON_DEBUG ++#ifdef CPTCFG_ATH9K_COMMON_SPECTRAL + void ath9k_cmn_spectral_init_debug(struct ath_spec_scan_priv *spec_priv, struct dentry *debugfs_phy); + void ath9k_cmn_spectral_deinit_debug(struct ath_spec_scan_priv *spec_priv); + +@@ -183,6 +183,6 @@ static inline int ath_cmn_process_fft(st + { + return 0; + } +-#endif /* CPTCFG_ATH9K_COMMON_DEBUG */ ++#endif /* CPTCFG_ATH9K_COMMON_SPECTRAL */ + + #endif /* SPECTRAL_H */ +--- a/local-symbols ++++ b/local-symbols +@@ -116,6 +116,7 @@ ATH9K_PCOEM= + ATH9K_HTC= + ATH9K_HTC_DEBUGFS= + ATH9K_HWRNG= ++ATH9K_COMMON_SPECTRAL= + CARL9170= + CARL9170_LEDS= + CARL9170_DEBUGFS= |
