      at86rf230: add support for calibration timeout · dce481e6
      由 Alexander Aring 提交于 
      This patch adds a handling for calibration if we are 5 minutes in PLL
state. I first tried to implement the calibration functionality in
TX_ON state via register values CF_START and DCU_START, but this occurs
a one second delay at each calibration time.

An another solution to start a calibration is to switch from TRX_OFF
state into TX_ON, then a calibration is done automatically by
transceiver. This method will be used in this patch, after each transmit
of a frame we check with jiffies if the PLL is set 5 minutes without
doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case
would be a transceiver in receiving mode only, but this is under normal
operation very unlikely.

      at86rf230: replace state change sleeps with hrtimer · eb3b435e
      由 Alexander Aring 提交于 
      This patch replace the state change timing relevant sleeps with
hrtimers. Currently the sleeps are done in the complete handler of
spi_async. The relation of doing the state change timing sleep with a
timer will get the sleep functionality out of spi_async complete handler
context.

      at86rf230: init xtal_trim with zero · e3721749
      由 Alexander Aring 提交于 
      This patch initialize xtal_trim value to zero. The xtal_trim property is
an optional device tree value. Currently if no xtal_trim property is
given the xtal_trim value can be contain random data, because it's a
stack variable. This patch init the xtal_trim value to zero which is
also the default value after reset for at86rf230 transceivers.

      at86rf230: remove interframe spacing time workaround · 24ccb9f4
      由 Alexander Aring 提交于 
      This patch removes the interframe spacing time workaround from at86rf230
driver and use the mac802154 one. The interframe spacing time differs at
at86rf212 and channel setting. This patch fix this handling which is also
a new workaround and should be moved into mac802154 while channel
setting.

      mac802154: add interframe spacing time handling · 61f2dcba
      由 Alexander Aring 提交于 
      This patch adds a new interframe spacing time handling into mac802154
layer. Interframe spacing time is a time period between each transmit.
This patch adds a high resolution timer into mac802154 and starts on
xmit complete with corresponding interframe spacing expire time if
ifs_handling is true. We make it variable because it depends if
interframe spacing time is handled by transceiver or mac802154. At the
timer complete function we wake the netdev queue again. This avoids
new frame transmit in range of interframe spacing time.

For synced driver we add no handling of interframe spacing time. This
is currently a lack of support in all synced xmit drivers. I suppose
it's working because the latency of workqueue which is needed to call
spi_sync.
