Hi,

This patch series includes a rework of the at86rf230 driver.

There are several changes:

 - Add regmap support.
 - Merge at86rf212 operations with generic at86rf2xx operations, all chips
   supports these operations.
 - Drop of irqworker. This is a workqueue which will scheduled by an irq to
   handle synchronous spi handling. Instead using asynchronous spi handling,
then no scheduler is involved at irq handling.
 - Also detected some bugs by receiving frame like CRC can be correct and a
   802.15.4 frame length could be above 127 bytes. This would crash the
whole kernel (but should be handled by the mac layer). Another bug is the
handling with RX_SAFE_MODE which protect the frame buffer after a readout.
This is currently not working because we read out the buffer twice and the
first one to get the frame size. Solution is to readout always the whole
frame buffer. - Added some timing relevants things from the datasheet for
state changes And IEEE 802.15.4 standard like interframe spacing.
Interframe spacing is needed to insert some receiving space time between
frame transmitting. This should be also handled by MAC layer, but it's
currently a workaround to add this inside the driver layer.
 - Add some callback setting for chip specific handling, instead of runtime
decisions if (is_chip_type()). Callbacks are set only once at probe time. -
We don't using a force state change anymore. A force state change will do a
abort of receiving frames while we want to transmit a new frame. This
should decrease the drop rate of packets.
 - And many others changes and bug fixes...
