* wlcore: determine AP extra rates correctlyArik Nemtsov2012-07-101-5/+15
| | | | | | | | | | | Don't use the ht_mode module parameter for determining AP supported rates. We can rely on channel type, since HT40 won't be enabled if our HT cap doesn't support it. Enable MIMO only if there enough antennas, and rely on per-peer rate limitation to prevent IOPs. Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl12xx/wl18xx: use a dynamic PS timeout of 1.5secArik Nemtsov2012-07-101-1/+1
| | | | | | | | 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>
* wlcore/wl12xx/wl18xx: check min FW versionArik Nemtsov2012-07-101-0/+4
| | | | | | | | | | Refuse to boot if the FW version is too old. The minimum version is set per chip, with the option of setting it per PG in the future. When boot fails because of an old FW, display a helpful message. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wlcore: enable sched scan while connectedVictor Goldenshtein2012-07-101-0/+1
| | | | | | | | | | | | New wl12xx firmware supports scheduled scans also while connected. Stop blocking sched scan requests when connected and add a quirk to block in hardware that don't support it (currently wl18xx doesn't). This requires FW version 6/7.3.10.2.112 for single-role and 6/7.5.6.0.25 for multi-role. Signed-off-by: Victor Goldenshtein <victorg@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: deprecate PG1 supportLuciano Coelho2012-06-261-38/+7
| | | | | | | | | The new PG2 version of the chip has a few differences in terms of FW API if compared to PG1. PG1 is just a sample that shouldn't be used in real life, so to avoid having to handle both separately, mark the PG1 version as deprecated and bail out during probe.

* wl18xx: use %zu for size_t arguments in printk callsLuciano Coelho2012-06-211-2/+2
| | | | | | | | | | | | | After 934b9d1e (wl18xx: avoid some -Wformat warnings) there was still a warning with (at least) ARM gcc version 4.4.1: drivers/net/wireless/ti/wl18xx/main.c: In function 'wl18xx_conf_init': drivers/net/wireless/ti/wl18xx/main.c:1026: warning: format '%ld' expects type 'long int', but argument 2 has type 'unsigned int' Fix this by using %zu for the both formats, since the fw->size and the macro (derived from sizeof()) are size_t.

* wl18xx: split siso40 HT cap between 2Ghz and 5GhzArik Nemtsov2012-06-211-5/+19
| | | | | | | | Remove the cap IEEE80211_HT_CAP_DSSSCCK40 from the 5Ghz variant of the siso40 HT capabilities. It is meaningless in 5Ghz. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: sane defaults for HT capabilitiesArik Nemtsov2012-06-211-30/+33
| | | | | | | | | | | | | | | 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.

* wl18xx: explicitly remove the 5Ghz MIMO HT capArik Nemtsov2012-06-211-14/+3
| | | | | | | | The 18xx chip does not support MIMO in 5Ghz. Use the siso20 HT cap as fallback in 5Ghz when "mimo" is requested. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: set Tx align quirk for PG2Arik Nemtsov2012-06-211-1/+1
| | | | | | | | | Before patch b5d6d9b (wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127x), this was automatically set for all platforms. As this should now be set explicitly, set it for PG2 as well. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: increase Rx descriptors for PG2Arik Nemtsov2012-06-211-1/+10
| | | | | | | | | | | New PG2 firmwares have additional Rx descriptors. Add a module parameter to manually set the number of Rx descriptors for older versions (PG1). We cannot discriminate based on chip-id, since this value must be set on probe. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wlcore: allow setting sleep_auth before interface initArik Nemtsov2012-06-211-0/+1
| | | | | | | | | | | | | | | | 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.

* wl18xx: clean up phy module parametersArik Nemtsov2012-06-081-56/+56
| | | | | | | | | | | | Give all wl18xx phy module paramters -1 as a default value, indicating the paramter was not set. Add previous default values to the default 18xx priv conf structure. Remove the board_type field from wl18xx priv. The field with the same name inside the phy conf is good enough for our purposes.

* wl18xx: read configuration structure from a binary fileLuciano Coelho2012-06-081-5/+63
| | | | | | | | | Instead of using the hardcoded configuration structure, try to read it from a "firmware" file called wl18xx-conf.bin. If the file doesn't exist, fall back to the hardcoded version. If the file exists but is illegal, bail out. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wlcore/wl18xx/wl12xx: use u8 instead of bool for host_fast_wakeup_supportLuciano Coelho2012-06-081-1/+1
| | | | | | | | | 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>

| | | | | | | | | | | | | | | | In PG2 only the last frame in the aggregate buffer should be aligned to the sdio block size. 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 Nemtsov2012-06-061-12/+84
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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>

| | | | | | | | | | | 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.
