2011-02-23ath9k_htc: Handle storage devicesSujith Manoharan
Some AR7010 based devices are recognized as storage media. Sending a CD-EJECT command to the device will 'convert' it into a WLAN device. Do this within the driver itself, removing the dependancy on an external program (usb_modeswitch). Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W.

2010-12-07ath9k_htc: Cleanup device identificationSujith Manoharan
ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc. Adding driver specific data to the shared structure would impact all the drivers. Handling USB device recognition for devices specific to ath9k_htc can be handled within the driver itself. Also, AR7010 refers to the processor used in both AR9280/AR9287 based devices. Rename the device enumerations accordingly. While at it, check properly for the bus type when choosing the EEPROM base address for UB95.

2010-11-08ath9k_hw: Fix AR9280 surprise removal during frequent idle on/offVasanthakumar Thiagarajan
Bit 22 of AR_WA should be set to fix the situation where chip reset is asynchronous to clock of analog shift registers, such that when reset is released, it could mess up the values of analog shift registers and cause some hw issue on AR9280. This bit is write only, but the driver does a read-modify-write on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave() during radio disable. This causes surprise removal of hw. It can never recover from this state and the hw will become usable only after a power on/off cycle, and sometimes only during a cold reboot. This issue can be triggered by doing frequent roaming with the simple/test-roam script available from the wifi-test project [1] when roaming between APs quickly. When roaming there is a is a high possibility that the device being put into idle (radio disable) state by mac80211 during AUTH->ASSOC. A device hardware reset would fail and the kernel would output: [40251.363799] ath: AWAKE -> FULL-SLEEP [40251.363815] ieee80211 phy17: device no longer idle - working [40251.363817] ath: Marking phy17 as not-idle [40251.363819] ath: FULL-SLEEP -> AWAKE [40251.415978] pciehp 0000:00:1c.3:pcie04: Card not present on Slot(3) [40251.419896] ath: ah->misc_mode 0x4 [40251.428138] pciehp 0000:00:1c.3:pcie04: Card present on Slot(3) [40251.532247] ath: timeout (100000 us) on reg 0x9860: 0xffffffff & 0x00000001 != 0x00000000 [40251.532250] ath: Unable to reset channel (2462 MHz), reset status -5 [40251.532422] ath: Set channel: 5745 MHz [40251.540639] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.548826] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.557023] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.565211] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.573415] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581603] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581606] ath: Failed to stop TX DMA.
