2012-02-15wl12xx: remove some dead code in wl1271_plt_init()Dan Carpenter1-2/+0
"ret" has already been checked at this point, and we don't need to check it again. This was left around from a previous patch 49d750ca14 "wl12xx: 1281/1283 support - New radio structs and functions".

2012-02-15wl12xx: delete wl->vif (and allow multiple vifs)Eliad Peller2-13/+0
Delete the global wl->vif (and the checks on it), so multiple vifs could be added. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: enter forced-psm on fw changeEliad Peller1-0/+15
Enter forced psm when changing fw, in order to make the sta a bit more disconnection-persistent. (DPM doesn't know about the incoming recovery, so it won't enter psm by itself) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: dynamically change fw according to number of active rolesEliad Peller4-13/+124
wl12xx uses different fw for single-role and multi-role scenarios (due to lack of space, some of the fw advanced features are disabled in the multi-role fw). Add checks on add_interfae and remove_interface in order to determine whether a fw switch is needed (and initiate recovery in this case).

2012-02-15wl12xx: Use a dedicated fw for PLTEliad Peller7-22/+52
A special PLT firmware is used for calibration. Add multiple fw support by introducing a new fw_type member, representing the currently saved fw (the actual fw state can be determined by wl->state).

2012-02-15wl12xx: add split_scan_timeout debugfs fileEyal Shapira1-0/+43
Add control over split_scan_timeout through debugfs. Values are in ms while 0 will disable split scan. Signed-off-by: Eyal Shapira <eyal@wizey.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: use split scan for normal scanEyal Shapira4-4/+15
Split scan allows the FW to schedule other activities during a scan which may be a long operation. This is achieved by setting a trigger TID to ANY_TID and a scan trigger timeout other than 0. The default one is set to 50ms.

2012-02-15wl12xx: don't fail on AP scanEliad Peller1-6/+7
AP role uses its own role_id for scans, so there's no reason to fail the scan if dev_role_id is invalid. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: declare support for hw scan while idleEliad Peller2-18/+2
By allowing hw scan while idle, we no longer need the redundant ROC/CROC that are done on idle off/on, which helps simplifying the state machine of the driver. This way, we can also allow scanning while there is an ongoing sched scan (otherwise, we won't be able to ROC on idle-off) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: configure arp filtering only after associationEliad Peller1-34/+35
We have to configure arp filtering only after the role was started, so move the BSS_CHANGED_ARP_FILTER handling after the join. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: Revert "wl12xx: disable auto-arp"Eliad Peller1-1/+2
This reverts commit e5e2f24b3eec67a7a35d43654a997f98ca21aff2. The encryption consideration on auto-arp configuration, along with a fw fix, seem to resolve the crashes that occured when auto-arp was enabled, so we can re-enable it now.

2012-02-15wl12xx: consider encryption and QoS in auto arp templateEliad Peller9-35/+117
When configuring the arp response template, and encryption is enabled, we should add some space and set the protected flag bit in the fc. In order to track the encryption type, set wlvif->encryption_type when setting an encryption key, and reconfigure the arp response. Clear this field on wl1271_join, as keys have to be re-configured anyway after a join command. Similarly, track whether QoS is configured.

2012-02-15wl12xx: add forced_ps modeEyal Shapira5-13/+32
For certain WiFi certification tests forcing PS is necessary. Since DPS is now enabled in the FW and this can't be achieved by using netlatency this required a new config option.

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.

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: use dev_role_id for scansEliad Peller3-8/+17

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 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.

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: 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.

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

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.
