2012-02-15wl12xx: change WLVIF_FLAG_PSM name and remove WLVIF_FLAG_PSM_REQUESTEDEyal Shapira4-36/+23
WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which marks that this vif is in AUTO PS. WLVIF_FLAG_PSM_REQUESTED is not required as mac80211 calls op_config with CONF_PS after association. wl12xx_config_vif() handling of CONF_PS was simplified and cleaned up.

2012-02-15wl12xx: enable/disable BET with AUTO_PS/ACTIVEEyal Shapira1-0/+7
While the FW with dynamic PS controls BET when going to PSM and back internally within the FW, there's still a need to enable it from the driver at least once (so enable on every entry to AUTO_PS) and disable it once we explicitly go back to STATION_ACTIVE_MODE. BET isn't relevant for 5GHz Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-02-15wl12xx: add dynamic_ps_timeout debugfs fileEyal Shapira1-0/+67
Enable read/write of dynamic_ps_timeout which controls the timeout of the dynamic PS implemented in the FW. dynamic_ps_timeout is the timeout (in msec) until going back to PS when there's no Rx/Tx Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: add support for HW dynamic PSEyal Shapira6-26/+26
FW now supports dynamic PS so we don't need to use mac80211 support. FW will go to PSM after a specified timeout with no Rx/Tx traffic. - Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter - The default PS mode would be dynamic PS - Default timeout is 100ms (same as it used to be in mac80211) - Avoid using mac80211 APIs to disable/enable dynamic PS as we're not using mac80211 PS control anymore. - COEX is handled by the FW while in dynamic PS so removed handling of SOFT_GEMINI Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-02-15wl12xx: fw api change - add role_id to tsf_infoEliad Peller3-6/+13

2012-02-15wl12xx: use dev_role_id for scansEliad Peller3-8/+17
Use device role for scans when the sta is not associated. sched_scan is used only when the sta is not associated, and thus should use the dev role (instead of sta role). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: fw api change - add role_id to set_templateEliad Peller6-53/+94
The set_template commands now takes the role_id as parameter. Usually, we'll use the vif's main role_id. However, sometimes we'll want to use wlvif->dev_role_id instead of wlvif->role_id, so pass the wanted role_id as param. Update WL127X_FW_NAME/WL128X_FW_NAME. (This commit starts a series of fw update patches, and changes the start() callback to return an error in order to prevent the use of the driver during the transition. This change will be reverted in the last patch of series) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-02-15Revert "wl12xx: Change claiming of the SDIO bus"Eliad Peller1-0/+10
This reverts commit 393fb560d328cc06e6a5c7b7473901ad724f82e7. Commit b6ad726 ("mmc: core: Prevent too long response times for suspend") fails the suspend if the mmc host can't be claimed before suspend. As the host is claimed by us as long as the chip is powered on, suspend will always fail. Revert to claiming the sdio bus only when needed.

2012-02-15wl12xx: remove wl1271_tx_update_filtersEliad Peller1-31/+0
wl1271_tx_update_filters() is used as some workaround to open filters while roaming on the same channel. However, it doesn't handle roaming to a different channel, and it might also sleep in the tx path, which is a bug. With the new auth/assoc redesign, roaming is much simpler, and this function is not needed anymore. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: check bss_conf->assoc on CHANGED_BSSIDEliad Peller1-1/+2
with the new auth/assoc redesign, we get CHANGED_BSSID indication before CHANGED_ASSOC indication, while our CHANGED_BSSID handling block assumes we are already associated.

2012-02-15wl12xx: remove unnecessary shadow declarationLuciano Coelho1-1/+2
The vif variable was being declared inside one of the internal blocks of wl1271_event_process. This is not necessary, since this variable is already declared in the function context. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: add testmode operation to read the BD_ADDR from Fuse ROMLuciano Coelho1-0/+50
Add a testmode command to retrieve the BD_ADDR that is stored in the Fuse ROM in newer PGs. In old PGs this operation is not supported. The caller can then derive the MAC addresses from it. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: use two MAC addresses based on the NVS or from fuse ROMLuciano Coelho5-26/+131
Add support for two MAC addresses. If the NVS has a valid MAC address, that takes precedence and we use two sequential address starting from the one specified. If the NVS doesn't contain a valid MAC address (ie. if it is set to 00:00:00:00:00:00), we check if the HW PG version in use has the BD_ADDR written in the fuse ROM. If it does, we read it and derive the two subsequent addresses for WLAN. During production, 3 addresses are reserved per device. The first for Bluetooth (burnt in the fuse ROM) and the following two for WLAN. This patch has some code by Igal and Arik (squashed from internal patches).

2012-02-15wl12xx: read chip ID and HW PG version during probeLuciano Coelho3-29/+46
In order to read the MAC addresses from the fuse ROM, we need to know the chip ID and the HW PG version. We need to know the MAC address during probe, because that's when we register our HW with mac80211. To prepare for that, this patch reads the chip ID and HW PG version during probe instead of doing it at boot time. We power the chip on briefly in order to do that. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: move partition table definition to io.cLuciano Coelho3-66/+68
Up till now we only needed to access the partition table in boot.c. But to add support for reading the MAC address from the FUSE in testmode, we will have to change the partition in testmode.c. Thus, we move the partition table to io.c and export it via io.h. It makes more sense to have it in the io part anyway. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: cancel delayed elp work and clear flags when stopping PLTLuciano Coelho1-3/+4
In some cases a race condition can happen if we don't cancel any pending ELP work before stopping PLT. With this commit we cancel ELP work and clear the wl->flags bitmask. Also clean up the wl elements after powering off. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: Fix potential interrupt stormIdo Yariv1-2/+28
The interrupt threaded handler exits immediately if the driver's state is WL1271_STATE_OFF. As a result, the interrupt status is not read. If the interrupt is level triggered, it will be fired again. Fix this by disabling interrupts before setting the state to OFF. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: Power off after flushing workIdo Yariv1-2/+5
When stopping plt, the chip is powered off before all current work items are flushed and interrupts are disabled. This might introduce a race in which the driver tries to communicate with a powered off chip. Fix this by powering off the device only after interrupts are disabled and all work items are flushed.

2012-02-15wl12xx: Acquire lock before stopping pltIdo Yariv1-13/+5
__wl1271_plt_stop is called from both wl1271_plt_stop and wl1271_unregister_hw. While wl1271_plt_stop acquires a mutex, wl1271_unregister_hw does not.

2012-02-15wl12xx: Make sure HW is available in sched scan opsPontus Fuchs1-0/+8
The sched_scan_(stop|start) ops fails to check for WL1271_STATE_OFF. This can lead to a race where the driver tries to access the HW while it's off.

2011-12-20wl12xx: mark no sched scan only after FW eventEyal Shapira2-2/+1
stop sched scan isn't an immediate operation and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID after sending a stop before changing internal state and notifying upper layers. Not doing this caused problems when canceling an existing sched scan and immediately requesting to start a new one with a different configuration as the FW was still in the middle of the previous sched scan.

2011-12-20wl12xx: fix sched scan of DFS channelsEyal Shapira1-7/+8
DFS channels weren't scanned properly because min/max_duration weren't set for these channels even though they're required by the FW. The change sets passive_duration and min/max_duration for all channels as the FW uses the correct parameters according to the channel type.

2011-12-20wl12xx: fix checking of started dev roleEliad Peller1-23/+18
dev_role_id only indicates whether the dev role is enabled, not started (e.g. on IBSS merge, the device role is enabled, but not started). Checking for any role in ROC (in order to determine whether dev role was started) is wrong as well, especially in multi-vif env. Check for started dev role only by checking the dev_hlid.

2011-12-20wl12xx: make WL1271_FLAG_IDLE flag per-vifEliad Peller4-6/+16
This flag should be set per-vif, rather than globally. Rename the flag to indicate IN_USE (rather than IDLE), as in the default configuration (i.e. flag is clear) the vif should be idle.

We need to set the extended radio parameters for wl127x only. Currently, we were only calling this command with wl127x STA mode, but we should also do it for AP mode.

2011-12-15wl12xx: don't write out of bounds when hlid > WL12XX_MAX_LINKSLuciano Coelho1-2/+6
We should not get an hlid value bigger than WL12XX_MAX_LINKS from wl1271_rx_handle_data(). We have a WARN_ON in case it happens. But despite the warning, we would still go ahead and write the hlid bit into active_hlids (a stack variable). This would cause us to overwrite other data in the stack. To avoid this problem, we now skip the write when issuing the warning, so at least we don't corrupt data. Signed-off-by: Luciano Coelho <coelho@ti.com>
