Hi all,
this patch series is v2 of my lastest at86rf230 patch serie. If all seems
fine I will send it to netdev later.
I already sent the lockdep splats fix to net which is a bugfix for stable.

changes since v2:
- change state change to STATE_TX_ON.
- add change reset timings patch.
-
This patch make the reset pin optionally. Some devices like the atben
from qi-hardware don't have a reset pin externally. The usually way is
to turn power off/on for the atben device to initiate a device reset.

There is no need to lock the clearing of IRQ_TRX_END in status.

This patch adds devicetree support for the at86rf230 driver.
Possible gpios to configure are "reset-gpio" and "sleep-gpio".
Also add support to configure the "irq-type" for the irq polarity
register.

While checkpatch another patch I got a:
"WARNING: msleep < 20ms can sleep for up to 20ms"
The datasheet of at86rf231 and at86rf212 says a minimum delay for reset
pulse width and spi access latency after reset is 625 nanoseconds.
This patch removes the 1 milliseconds sleep and replace it with a 1
This patch fix a unexpected state change for the at86rf231 chip.
We can't change into STATE_FORCE_TX_ON while the chip is in one of
SLEEP, P_ON, RESET, TRX_OFF, and all *_NOCLK states.
In this case we are in the TRX_OFF state. See datasheet [1] page 71 for
more information.
