2008-08-22libertas: support boot commands to write persistent firmware and bootloaderBrian Cavagnolo
Add locking and non-locking versions of if_usb_prog_firmware to support programming firmware after and before driver bring-up respectively. Add more suitable error codes for firmware programming process. Add capability checks for persistent features before attempting to use them. Based on patches from Brajesh Dave and Priyank Singh.

2008-04-16libertas: convert libertas driver to use an event/cmdresp queueHolger Schurig
This patch (co-developed by Dan Williams and Holger Schurig) uses a kfifo object for events and a swapping buffer scheme for the command response to preserve the zero-copy semantics of the CF driver and keep memory usage low. The main thread should only ever touch the buffer indexed by priv->resp_idx, while the interface code is free to write to the second buffer, then swap priv->resp_idx under the driver spinlock. The firmware specs only permit one in-flight command, so there will only ever be one command response to process at a time.

2008-01-28libertas: switch USB cardp->priv to 'struct lbs_private *' and resulting fixDavid Woodhouse
Amazing what interesting things the compiler will tell you if you let it know what types you expect to be passing around. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: switch to a waitqueue and timer for handling USB firmware loadDavid Woodhouse
No need to busy-wait, even if we did have a 100ms delay in the loop. This makes it easier to support the new 'firmware ready' event which is in the new firmware, too. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28libertas: reset devices upon disconnect rather than module unloadingAndres Salomon
1) Do not reset libertas devices upon module unload. We're unloading the module, we're not killing off devices. 2) Instead, reset libertas devices inside if_usb_disconnect, as we're killing off interfaces and so on. 3) Resetting via disconnect callback means we no longer need to keep track of probed libertas devices; kill off that list (and its wonderful lack of locking..), as well. Drop a useless comment as well. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28libertas: move to uniform lbs_/LBS_ namespaceHolger Schurig
This patch unifies the namespace of variables, functions defines and structures. It does: - rename libertas_XXX to lbs_XXX - rename LIBERTAS_XXX to lbs_XXX - rename wlan_XXX to lbs_XXX - rename WLAN_XXX to LBS_XXX (but only those that were defined in libertas-local *.h files, e.g. not defines from net/ieee80211.h) While passing, I fixed some checkpatch.pl errors too.

2007-10-10[PATCH] libertas: reorganize and simplify init sequenceDan Williams
This patch moves all firmware load responsibility into the interface-specific code and gets rid of the firmware pointer in the generic card structure. It also removes 3 fairly unecessary callbacks: hw_register_dev, hw_unregister_dev, and hw_prog_firmware. It also makes the init sequence from interface probe functions more logical, as there are paired add/remove and start/stop calls into generic libertas code. Because the USB driver code uses the same TX URB callback for both firmware upload (where the generic libertas structure isn't initialized yet) and for normal operation (where it is), some bits of USB code have to deal with 'priv' being NULL. All USB firmware upload bits have been changed to not require 'priv' at all, but simply the USB card structure. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2007-10-10[PATCH] libertas: make more functions static & remove unused functionsHolger Schurig
Some functions where declared in header files, but used only once. They are now static functions. After doing this, I found out that some functions weren't used at all. I removed this dead code.

2007-06-11[PATCH] libertas: fix RESET logic at unload timeHolger Schurig
Previously, we had a fixed array of 5 elements where we remembered all initialized devices. This has been changed to use a "struct list_head" organization, which is IMHO cleaner. Also renamed usb_cardp to cardp, as in the reset of the code. Renamed reset_device() to if_usb_reset_device() like many other functions.
