2013-04-16at86rf230: change irq handling to prevent lockups with edge type irqSascha Herrmann
Implemented separate irq handling for edge and level type interrupt configuration. For edge type interrupts calls to disable_irq_nosync() and enable_irq() are removed. The at86rf230 resets the irq line only after the irq status register is read. Disabling the irq can lock the driver in situations where a irq is set by the radio while the driver is still reading the frame buffer. With irq_type configuration set to 0 the original behavior is preserverd. Additional the irq filter register is set to filter out all unused interrupts and the irq status register is read in the probe function to clear the irq line.

2013-04-16at86rf230: add irq type configuration optionSascha Herrmann
Add option to at86rf230 platform data to configure the type of the interrupt used by the driver. The irq polarity of the device will be configured accordingly. Signed-off-by: Sascha Herrmann <sascha@ps.nvbi.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-08mrf24j40: Enable link-layer acknowledgement and retryAlan Ott
On the MRF24J40, link-layer acknowledgment request and retry must be turned on explicitly for each packet. Turn this on in the hardware based on the FC_ACK_REQ bit being set in the packet. Also, now that failure to receive an ACK will cause the hardware to report failure of transmission, change the log level for this failure to debug level.

2013-04-08at86rf230: remove unnecessary / dead codeSascha Herrmann
In at86rf230_probe() lp was first set to dev->priv and a few lines later dev->priv was set to lp again, without changing lp in between. The call to ieee802154_unregister_device() before err_irq: was unreachable. Signed-off-by: Sascha Herrmann <sascha@ps.nvbi.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-08IEEE 802.15.4: remove get_bsn from "struct ieee802154_mlme_ops"Werner Almesberger
It served no purpose: we never call it from anywhere in the stack and the only driver that did implement it (fakehard) merely provided a dummy value. There is also considerable doubt whether it would make sense to even attempt beacon processing at this level in the Linux kernel.

Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-10-02workqueue: avoid using deprecated functionsLinus Torvalds
The network merge brought in a few users of functions that got deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the same as the regular system_wq, since all workqueues are now non- reentrant. Similarly, remove one use of flush_work_sync() - the regular flush_work() has become synchronous, and the "_sync()" version is thus deprecated as being superfluous.

2012-08-30drivers/ieee802154: move ieee802154 drivers to net folderalex.bluesman.smirnov@gmail.com
The IEEE 802.15.4 standard represents a networking protocol. I don't exactly know why drivers for this protocol are stored into the root 'driver' folder, but better will be to store them with other networking stuff. Currently there are only 3 drivers available for IEEE 802.15.4 stack, so lets do it now with the smallest overhead.
