2012-01-05ath6kl: revert USB supportJohn W. Linville
The ath6kl driver is causing build failures when the ath6kl bits are not built as modules. A better fix is forthcoming in a future release, but for now lets revert the problematic code. This reverts the following commits: fde57764ef8751b9aca11b6f6221ac5555bda699 d70385a26ad9a122a5450d066550470107b6bc38 59d954dda4b9b3f3e61d4b87a2b26952b8c4c09d Signed-off-by: John W.

2011-12-23ath6kl: add support for FW API 3Kalle Valo
As firmware starting from 3.2.0.12 has some API changes and doesn't work with older versions of ath6kl we need to bump up the API version. This way we don't break anything. Also store which version of API is used and print that during boot: ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.13 api 3 Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-23ath6kl: handle firmware names more dynamicallyKalle Valo
Currently ath6kl has just hardcoded paths to each firmware file. Change this more dynamic by separating the the directory and file name from each other. That way it's easier to dynamically create full paths to firmware and code looks better. And now it's possible to remove a function needed by devicetree code. While at it add a structure inside struct ath6kl_hw to contain all firmware names. I deliberately omitted board file support as those will be handled later. This is needed for firmware API 3.

2011-12-23ath6kl: Send own IP addr to the firmware during WOW suspendRaja Mani

2011-12-14ath6kl: support for P2P mgmt operations on station interfaceAarthi Thiruvengadam
This patch enables support for doing P2P management operations like device discovery on top of a station interface. After group formation, the station interface will become a P2P GO/client interface as the case may be. This feature requires modifications to a couple of existing WMI structures and therefore new command ids and structures have been defined in order to be compatible with older firmware versions and other chips. The exception here is the wmi_connect_cmd. Adding a new field to the end of the structure will not cause any issues with previous firmware versions since firmware only checks for minimum length of the command. The other structures are of variable length, hence it was not possible to add new fields to the end. The new command ids have to be added to the end of enum wmi_cmd_id, so it has updated to match the firmware. The driver will support both the 'old' and the 'new' commands for a while by checking the firmware capabilities.

2011-12-13ath6kl: implement scheduled scanKalle Valo
ath6kl firmware supports scheduled scan functionality with the wow ssid filter. But the firmware does not send any events after scan results so I had to add a timer which notifies about new scan results. Sched scan needs firmware version 3.2.0.6 or later.

2011-11-21ath6kl: Use mutex to protect dma buffer in sync read writeRaja Mani
Firmware crashes while starting Soft AP in 32 bit x86 platform. The reason is that the single dma buffer (ar_sdio->dma_buffer) is used in ath6kl_sdio_read_write_sync() for unaligned buffer handling and this function is called in the multiple context at the same time. So, finally hits dma buffer corruption and firmware crash. Mutex is used to protect dma buffer to avoid data corruption. Spin lock can not used to fix this issue since mmc stack read/write calls may for sleep.

2011-11-16ath6kl: Fix AP mode operation after interface down/upVasanthakumar Thiagarajan
When operating AP interface is brough down the mode is reset to STA. This STA will be reconfigured into AP mode when the interface is brought up again. This sequence will be successful only when change_virtual_intf() returns with no error, but there is a check in this callback which does the type change only when that interface is active. This callback does nothing more than saving the new interface type to vif and wdev, so the sanity check for interface state and wmi state is not necessary.
