* wl12xx/wl18xx: use a dynamic PS timeout of 1.5secArik Nemtsov2012-07-10
| | | | | | | | It seems some parties have bad user experience when smaller values are used. This should have little implications for power consumption, since traffic is bursty in nature. Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl12xx/wlcore: increase FW filename versionLuciano Coelho2012-07-10
| | | | | | | | | | | | We have some API changes and new features in the new firmwares that are not compatible with older drivers. Increase the version of the FW filenames for wl12xx to 5. Additionally, remove the duplicate definitions from wlcore_i.h and remove the MODULE_FIRMWARE macro calls from the SDIO and SPI modules, since they're irrelevant there.

* wlcore: add probe request templates for sched and one-shot scansYoni Divinsky2012-07-10
| | | | | | | | | | | | | | | The driver configures the firmware template for probe requests during the scan process. If the same template is used for one-shot and sched scans they will override each other when running scans simultaneously. This fix works only on firmwares later than X.3.9.2.112 for single role and X.3.9.2.23 for multi-role.

* wl18xx: sane defaults for HT capabilitiesArik Nemtsov2012-06-21
| | | | | | | | | | | | | | | Introduce a default set of HT capabilities that are set according to the number of antennas on the board. Move the HT setting code down to allow the number of antennas to be set (and optionally overridden) before it. Remove the "mimo" HT option, since the default mode now enables MIMO is possible. Use this opportunity to add a helper function for setting HT capabilities and reduce the volume of the code a bit.

* wlcore: allow setting sleep_auth before interface initArik Nemtsov2012-06-21
| | | | | | | | | | | | | | | | Hold a value for sta_sleep_auth that is amenable to change by debugfs. When detecting a legal value in this variable on interface init, use it as an override value for sleep_auth. This makes debugging more intuitive using the debugfs value. Increment the conf version since we added an element to the conf structure. Note: An AP going up will always set sleep_auth to PSM_CAM.

* wlcore/wl12xx: add support for HP and SKW FEM radio manufacturersYair Shapira2012-06-13
| | | | | | | | | | | | | | | | | | Add support for HP (High Performance TQS fem type 3) and SKW (fem type 2). This is done by increasing the number of FEM manufacturers to 4. Usually FEM parameters from ini file are read from nvs file and passed to firmware using TEST_CMD_INI_FILE_RADIO_PARAM. Still, because the nvs file has only place for 2 FEMs, we need to pass the new FEM types information in one of the available entries. This is done by mapping new fem types 2,3 to entry 0. This solution works for manual FEM selection. AutoDetect-FEM still support only fem types 0 and 1. Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wlcore/wl18xx/wl12xx: use u8 instead of bool for host_fast_wakeup_supportLuciano Coelho2012-06-08
| | | | | | | | | The conf structure is going to be exported to a file, so we should use only well defined types. bool is not well defined and may vary from platform to platform, so change the host_fast_wakeup_support type to u8 instead. Signed-off-by: Luciano Coelho <coelho@ti.com>

This frame's header msb should be set to 0, while in all the previous frames in the aggregation buffer, this bit should be set to 1. [Add a HW op for setting the frame ctrl bit only for 18xx.

| | | | | | | | | | | | | | In PG2, the HW watchdog interrupt occupies bit0 of the event vector, and the SW watchdog is relocated to bit9.

* wlcore/wl12xx/wl18xx: implement op_set_key per HW archArik Nemtsov2012-06-06
| | | | | | | | | | | | | The 12xx set_key just calls the common wlcore_set_key function, in order to program the keys into the FW. The 18xx variant changes the spare block count when a GEM or TKIP key is set. Also modify the get_spare_blocks HW op for 18xx to return the correct numbers of spare blocks, according to what is currently set in FW.

* wlcore/wl12xx/wl18xx: handle spare blocks spacial cases per archArik Nemtsov2012-06-06
| | | | | | | | | | | | | | | Add a HW op for getting spare blocks. 12xx cards require 2 spare blocks for GEM encrypted SKBs, regardless of VIFs or keys programmed into the FW. 18xx cards require 2 spare blocks when there are any connected TKIP or GEM VIFs. For now always return 2 spare blocks, as this works with all networks. The special case TKIP/GEM functionality is added at a later patch.

* wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127xLuciano Coelho2012-06-05
| | | | | | | | | | | | | | | Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke support for wl127x chips. When we moved the identify_chip operation to an earlier stage (ie. to the probe function), we broke wl127x support because during HW init we would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN. To avoid this, set this quirk in the identify_chip operations and only force it to be unset if the bus module doesn't support it. We were doing the opposite and setting the flag if the bus module supports it. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wlcore/wl12xx/wl18xx: move lower driver debugfs to a subdirLuciano Coelho2012-06-05
| | | | | | | | | | | Instead of adding more files from the lower drivers into the same directory in debugfs as wlcore, we now add a subdirectory for the lower driver. This makes things a bit easier, because we can quickly see where the debugfs entry is implemented and what is specific to the lower driver.

| | | | | | | | | | | | | | The number of RX packet descriptors may vary from chip to chip and in different firmware versions. Unfortunately, the array that contains the actual descriptors is in the middle of the fw_status structure. To manage this, we split the struct into two so we can calculate the offset of what comes after the array and access the last elements more easily.
