2011-11-08wl12xx: change blocksize alignment quirk to negativeLuciano Coelho
SDIO blocksize alignment support is now the rule, not the exception. To simplify the code in patches to come, invert the meaning of the quirk to be negative (ie. the quirk is set if the device does _not_ support blocksize alignment). Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-11-08wl12xx: clear wl->vif on remove_interfaceEliad Peller
wl->vif should be cleared on remove_interface() (rather than on stop()) even when only a single vif is supported, because during vif mode change stop() might not get called (e.g. because of monitor interface existence) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-11-08wl12xx: add vifs_state debugfs keyEliad Peller
Add debugfs key to dump information regarding the active vifs (similar to the driver_state debugfs key) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-11-08wl12xx: keep beacon-filtering enabled during STA operationArik Nemtsov
Enable beacon filtering on STA init, and don't disable it when entering active mode. Otherwise dynamic-PS supports means we receive beacons from the current AP during any Tx/Rx performed by the driver. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-11-08wl12xx: reconfigure rate policies on set_bitrate_maskEliad Peller
The rate policies are configured only after association, resulting in auth req being sent in wrong rates. Reconfigure rate policies on bitrate mask change. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-11-08wl12xx: couple role_start_dev with rocEliad Peller
Device role is always started along with ROC. Couple them together by introducing new wl12xx_start_dev and wl12xx_stop_dev functions. By using these functions, we solve a bug that occured during channel switch - we started the dev role on one channel, and ROCed on a different one.

2011-10-11wl12xx: handle injected packetsEliad Peller
Injected packets are sent with no vif, causing the wl12xx to NULL-dereference in multiple places. Furthermore, injected packets are currently not sent at all, as system_hlid doesn't belong to any specific role, so wl1271_skb_dequeue() never return its packets. Handle both these problems.

2011-10-11wl12xx: use the same plat dev name for both SPI and SDIOLuciano Coelho
There's no need to have the bus name included in the platform device name that we create. The core driver doesn't need to know about the type of bus it uses. Any differences between the buses that need to be handled differently in the core, can be passed in the platform data (as the pwr_in_suspend boolean does). Use "wl12xx" for the device name in both bus drivers. Rename the platform driver name to "wl12xx_driver", just to differentiate from the platform device names.

2011-10-11wl12xx: remove warning message during IBSS TxShahar Lev
mac80211 sets the carrier on an IBSS interface even when no network is joined. Ignore garbage frames transmitted on a disconnected IBSS interface without printing warnings. Signed-off-by: Shahar Lev <shahar@wizery.com> [merged with wlvif changes] Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: spi: use dev_err instead of wl1271_errorLuciano Coelho
To prevent a useless dependency between the spi module and the wl12xx module, we need to replace the wl1271_error macros with dev_err. At the same time, remove the SPI data hexdump, since this produces way too much data and is not particularly useful. There's no print_hex_dump() equivalent for dynamic debug, so it's hard to control when the dumps are printed out. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: sdio: use dev_dbg instead of wl1271_debugLuciano Coelho
To prevent a useless dependency between the sdio module and the wl12xx module, we need to replace the wl1271_debug macros (and friends) for dev_dbg and other equivalents. At the same time, remove the SDIO data hexdump, since this produces way too much data and is not particularly useful. There's not print_hex_dump() equivalent for dynamic debug, so it's hard to control when the dumps are printed out. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: move debugging definitions to a separate fileLuciano Coelho
Separate the debugging macros and other definitions to a new debug.h file. This is be needed because the sdio and spi modules don't need to depend on the wl12xx module anymore, but still need to include wl12xx.h. Currently they do depend on it, because of the debugging global that wl12xx exports. A future patch will remove this dependency. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: drop unneeded plat_devFelipe Balbi
now that useless plat_dev is unnecessary, we can remove it. Signed-off-by: Felipe Balbi <balbi@ti.com> [forward ported and fixed sysfs file creation] Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: mark some symbols staticFelipe Balbi

2011-10-11wl12xx: move common init code from bus modules to mainFelipe Balbi
Move all common parts from sdio.c and spi.c to main.c, since they now can be handled as part of the platform driver. Signed-off-by: Felipe Balbi <balbi@ti.com> [forward-ported, cleaned-up and rephrased commit message] [added a bunch of fixes and a new pdata element] [moved some new code into main.c as well] Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: add platform driver to the core moduleFelipe Balbi
Nnow that we have a platform_device on both glue layers, add a platform_driver to the core driver. It's currently an empty platform_driver but more functionality will be added on later patches.

2011-10-11wl12xx: add an spi glue struct to keep wl and device side-by-sideFelipe Balbi
In order to fully abstract the bus, we need to save the device structure *beside* wl1271, instead of inside it. This will help re-structuring the driver so that we avoid the duplicated code in the bus modules.

2011-10-11wl12xx: remove sdio_test moduleLuciano Coelho
This module has been causing more trouble than being useful. It only tests the SDIO speed by connecting to the wl12xx chip and does some throughput calculations. It is an ugly quick hack and, if we really want to have it as part of wl12xx we need to clean it up and implement it properly. A tarball of the code has been created and posted here, with some instructions: http://wireless.kernel.org/en/users/Drivers/wl12xx#SDIO_performance_test_module Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: use round-robin policy for txEliad Peller

2011-10-11wl12xx: replace all remaining wl->vif referencesEliad Peller
wl->vif is appropriate only when a single vif is being used. Instead, pass wlvif as parameter or iterate through all the vifs (e.g. when a global configuration was changed) Leave wl->vif only to determine whether a vif was already added (this check will be removed as well after both the driver and fw will support multiple vifs) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-10-11wl12xx: add power_level field to wlvifEliad Peller
move power_level into the per-interface data. mac80211 configures some values (e.g. band, channel) globally, while we configure them per-interface.

2011-10-11wl12xx: refactor fw init into a new functionEliad Peller
The fw boot and initialization currently happens inside the add_interface() callback. This is wrong, as add_interface is called for each new vif.
