2011-05-10bcma: add Broadcom specific AMBA bus driverRafał Miłecki
Broadcom has released cards based on a new AMBA-based bus type. From a programming point of view, this new bus type differs from AMBA and does not use AMBA common registers. It also differs enough from SSB. We decided that a new bus driver is needed to keep the code clean. In its current form, the driver detects devices present on the bus and registers them in the system. It allows registering BCMA drivers for specified bus devices and provides them basic operations. The bus driver itself includes two important bus managing drivers: ChipCommon core driver and PCI(c) core driver. They are early used to allow correct initialization. Currently code is limited to supporting buses on PCI(e) devices, however the driver is designed to be used also on other hosts. The host abstraction layer is implemented and already used for PCI(e). Support for PCI(e) hosts is working and seems to be stable (access to 80211 core was tested successfully on a few devices). We can still optimize it by using some fixed windows, but this can be done later without affecting any external code. Windows are just ranges in MMIO used for accessing cores on the bus.

2011-05-05mac80211: add basic support for WoWLANJohannes Berg
This adds basic support for the new WoWLAN configuration in mac80211. The behaviour is completely offloaded to the driver though, with two new callbacks (suspend/resume). Options for the driver include a complete reconfiguration after wakeup, and exposing all the triggers it wants to support.

2011-05-05nl80211/cfg80211: WoWLAN supportJohannes Berg
This is based on (but now quite far from) the original work from Luis and Eliad. Add support for configuring WoWLAN triggers, and getting the configuration out again. Changes from the original patchset are too numerous to list, but one important change needs highlighting: the suspend() callback is passed NULL for the trigger configuration if userspace has not configured WoWLAN at all.

2011-05-05cfg80211: Remove unused wiphy flagJouni Malinen
The only user of WIPHY_FLAG_SUPPORTS_SEPARATE_DEFAULT_KEYS was removed and consequently, this flag can be removed, too. In addition, a single capability flag was not enough to indicate this capability clearly since the device behavior may be different based on which operating mode is being used.

2011-04-28Bluetooth: Add store_hint parameter to mgmt_new_keyJohan Hedberg
Even for keys that shouldn't be stored some use cases require the knowledge of a new key having been created so that the conclusion of a successful pairing can be made. Therefore, always send the mgmt_new_key event but add a store_hint parameter to it to indicate to user space whether the key should be stored or not.

2011-04-28Bluetooth: Fix link key persistent storage criteriaJohan Hedberg

2011-04-28Bluetooth: Add confirm_hint parameter to user confirmation requestsJohan Hedberg
When accepting a pairing request which fulfills the SSP auto-accept criteria we need to push the request all the way to the user for confirmation. This patch adds a new hint to the user_confirm_request management event so user space can know when to show a numeric comparison dialog and when to show a simple yes/no confirmation dialog.

2011-04-28Bluetooth: Add variable SSP auto-accept delay supportJohan Hedberg
Some test systems require an arbitrary delay to the auto-accept test cases for Secure Simple Pairing in order for the tests to pass. Previously when this was handled in user space it was worked around by code modifications and recompilation, but now that it's on the kernel side it's more convenient if there's a debugfs interface for it.

2011-04-19mac80211: add a function for setting the TIM bit for a specific stationFelix Fietkau
This allows a driver to buffer frames for a PS station and tell mac80211 to wake it up even though mac80211 does not have any buffered frames for it. This is necessary for properly handling aggregation related buffering, in ath9k, because the driver needs to keep its frames in order to keep track of the Block-ACK window.

2011-04-19wl12xx: Handle platforms without level trigger interruptsIdo Yariv
Some platforms are incapable of triggering on level interrupts. Add a platform quirks member in the platform data structure, as well as an edge interrupt quirk which can be set on such platforms. When the interrupt is requested with IRQF_TRIGGER_RISING, IRQF_ONESHOT cannot be used, as we might miss interrupts that occur after the FW status is cleared and before the threaded interrupt handler exits. Moreover, when IRQF_ONESHOT is not set, iterating more than once in the threaded interrupt handler introduces a few race conditions between this handler and the hardirq handler. Currently this is worked around by limiting the loop to one iteration only. This workaround has an impact on performance. To remove to this restriction, the race conditions will need to be addressed.

2011-04-12mac80211: Check for queued frames before entering power save.Vivek Natarajan
In a highly noisy environment, the tx rate of the driver drops and the application slows down since it has not yet received ACKs for the frames already queued in the hardware. Since this ACK may take more than 100ms, stopping the dev queues for entering PS at this stage breaks applications, WMM test cases in my testing. If there are frames already pending in the tx queue, postponing the PS logic helps to avoid redundant queue stops. When power save is enabled by default and in a noisy environment, this API certainly helps in improving the average throughput.
