Hi, This patch series is a rework of the at86rf230 driver. There are several changes:
- Regmap support. - Drop of irqworker. This is a workqueue which will scheduled by an irq to handle synchronous spi handling. Instead using asynchronous spi handling, so 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 frame 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... I will send this series when to netdev when I get response if it still work on at86rf212 :-). In this time we can test the new driver implementation. My tests shows a speedup of 1 ms for a 6LoWPAN ping without fragmentation and a decrease of the drop rate. I have a at86rf231 chip only and I test it in ARET mode as well without any problems. It would be nice I get some testing reviews from other at86rf2xx chips. The changes are also available at github see: https://github.com/linux-wpan/wpan-next/commits/at86rf230_rework - Alex changes since v2: There was some huge change. - remove driver rename. - fix ieee802154_register_device error handling. - async transmit handling: - do more state change like the programming model guide. - add a assert which check only once the state change. - add support for checking trac status. - fix the race condition from RX_AACK_ON -> RX_AACK_BUSY check.
