Sometimes the async state function is call in an context where the spi irq is diabled. This patch fix the handling to enable the irq when spi_async failed in the async state change calling chain.

When the driver waits for a tx completion currently the driver direct enables the irq. When we switching to RX_AACK_ON some steps afterwards the driver could receive a new frame and request resources which are already in use, for example irq state change resource. To be sure there are no new interrupts when we switching to RX_AACK_ON, we enable the irq when state change to RX_AACK_ON was completed.

This patch is a complete reimplementation of transmit and receive handling for the at86rf230 driver. It solves also six bugs: First: The RX_SAFE_MODE is enabled and the transceiver doesn't leave the receive state while the framebuffer isn't read by a CMD_FB command. This is useful to read out the frame and don't get into another receive or transmit state, otherwise the frame would be overwritten. The current driver do twice CMD_FB calls, the first one leaves this protection. Second: Sometimes the CRC calculation is correct and the length field is greater 127. The current mac802154 layer and filter of a at86rf2xx doesn't check on this and the kernel crashes. In this case the frame is corrupted, we send the whole receive buffer to the next layer which can be useful for sniffing. Thrid: There is a undocumented race condition. When we are go into the RX_AACK_ON state the transceiver could be changed into RX_AACK_BUSY state. This is a normal behaviour. In this case the transceiver received a SHR while assert wasn't finished. Fourth: It also handle some more "correct" state changes. In aret mode the transceiver need to go to TX_ON before the transceiver go into RX_AACK_ON. Fifth: The programming model [0] describes also a error handling in ARET mode if the trac status is different than zero. This is patch adds support for handling this. Sixth: In receive handling the transceiver should also get the trac status according [0]. The driver could use the trac status as error statistic handling, but the driver doesn't use this currently. There is maybe some timing behaviour or the read of this register change some transceiver states. In addition the irqworker is removed. Instead we do async spi calls and no scheduling is involved anymore. The transmit function is also asynchron but with a wait_for_completion handling. The mac802154 layer doesn't support asynchron transmit handling right now. The state change behaviour is now changes, before it was: 1. assert while(!STATE_TRANSITION_IN_PROGRESS) 2. state change 3. assert while(!STATE_TRANSITION_IN_PROGRESS) 4. assert once(wanted state != current state) Sometimes a unexcepted state change occurs when 4. assert was violated. The new state change behaviour is: 1. assert while(!STATE_TRANSITION_IN_PROGRESS) 2. state change 3. wait state change timing according datasheet 4. assert once(wanted state != current state) This behaviour is described in the at86rf231 software programming model [0]. The state change documentation in this programming guide should also valid for at86rf212 and at86rf233 chips. The transceiver don't do a FORCE_TX_ON while we want to transmit a PDU. The new behaviour is a TX_ON and wait a receiving time (tFrame + tPAck). If we are still in RX_AACK_BUSY then we transmit a FORCE_TX_ON as timeout handling. The different is that FORCE_TX_ON aborts receiving and TX_ON waits if RX_AACK_BUSY is finished. This should decrease the drop rate of packets.

This patch adds new mac802154 hw flags for transmit power, csma and listen before transmit (lbt). These flags indicates that the transceiver supports these features. If the flags are set and the driver doesn't implement the necessary functions, then ieee802154_register_device returns -ENOSYS "Function not implemented". This patch merges also all at86rf230 operations into one operations structure and set the right hw flags for the at86rf230 transceivers.

Commit 8eba0eef ("at86rf230: remove irq_type in request_irq") removed the trigger configuration when requesting an irq, and instead relied on the interrupt trigger to be properly configured already. This does not seem to be an assumption that can be safely made, since boards disable all interrupt triggers on boot. On these boards, force the irq to trigger on rising edge, which is also the default for the chip. Signed-off-by: NPhoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: NDavid S.
