at86rf230: change irq handling to prevent lockups with edge type irq

2013-04-16T20:34:08+00:00

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.

at86rf230: add irq type configuration option

2013-04-16T20:34:07+00:00

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.

mrf24j40: Enable link-layer acknowledgement and retry

2013-04-08T16:09:18+00:00

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.

at86rf230: remove unnecessary / dead code

2013-04-08T16:00:16+00:00

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.

IEEE 802.15.4: remove get_bsn from "struct ieee802154_mlme_ops"

2013-04-08T16:00:16+00:00

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.

net: ieee802154: mrf24j40: use spi_get_drvdata() and spi_set_drvdata()

2013-04-07T20:48:18+00:00

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.
