This patch changes the irq trigger type value while calling devm_request_irq by using IRQF_TRIGGER_LOW when no irq type was given. Additional we add support for change the irq polarity while hw init if high level or low level triggered irq type are given. For rising edge triggered irq's the mrf24j40 can't deal with that, this races at position of tx completion irq, while the irq is disabled we readout the irq status registers. This will resets the irq line so other irq's can occur. Wile readout the irq status register the irq is still disabled and edge triggered interrupts will be ignored. Signed-off-by:

This patch supports setting of transmit power for the mrf24j40ma transceiver only. The mrf24j40mc has some amplifier to change the transmit power, I am currently not sure how the mapping for this amplifier looks like. Signed-off-by:

This patch adds supports to change the CSMA parameters. The datasheet doesn't say anything about max_be value. Seems not configurable and we assume the 802.15.4 default. But this value must exists because there is a min_be value. Signed-off-by:

This patch removes the threaded irq handling and do a hardirq instead. We need to switch to spi_async for this step for getting the irq status register. Reviewed-by:

This patch prepares that we can do the receive handling inside interrupt context by using spi_async. This is necessary for introduce a non-threaded irq handling. Also we drop the bit setting for "RXDECINV" at register "BBREG1", we do a driectly full write of register "BBREG1", because it contains the bit RXDECINV only. Reviewed-by:

This patch reworks the current transmit API to spi_async handling. We removed the error handling check, because mac802154 has no chance to report it. Also the transmit timeout handling can't be handled by xmit async handling, for this usecase we need to implement the netdev watchdog. These are all unlikely cases which we drop now and should be provided by netdev watchdog. We also drop the bit setting for TXNACKREQ at register TXNCON, this is not necessary. The TXNCON register should set only once for each frame, previous settings doesn't matter. Reviewed-by:

This patch introduce two static inline functions. The first to get the frame control field from an sk_buff. The second is for checking on the acknowledgment request bit on the frame control field. Later we can introduce more functions to check on the frame control fields. These will deprecate the current behaviour which requires a host-byteorder conversion and manually bit handling.

This patch uses the regmap functions for transceiver register settings where it's possible. This means everything except the hotpaths like receive/transmit handling. Reviewed-by:

This patch introduce regmap support for short and long address space of mrf24j40. It's only possible to use regmap_read/write/update_bits for long address range. This is because I added lowlevel bus operation because the write operation need to set the 12th bit to mark a register write, but regmap only supports to set bits for register write access in the first byte. We use other regmap register functions than read/write/update_bits, so this should be fine. Reviewed-by:

This patch adds support for edge triggered irq types. We remove the locking for irq resources by enable/disable irq and allocate directly some heap buffer at isr. We have still a enable/disable irq path but this is for level-triggered irq's which need to be disabled until spi_async clear the irq line. There is usually a little race condition between "irq line cleared" and "enable_irq". When in this time a edge triggered irq arrived, we will not recognize this interrupt. This case can't happend at at86rf230. The reason is that we unmask TRX_END irq's only which indicates a transmit or receive completion, which depends on the current state. On Transmit: TRX_END arrived and transceiver is in TX_ARET_ON state again, in this state no other TRX_END can happen until we leave the state. On Receive: This is protected with the RX_SAFE_MODE bit which leaves the transceiver in RX_AACK_BUSY until we readed the framebuffer. In this state no other TRX_END can happen. Tested with RPi where I first detected issues between edge/level irq's. Signed-off-by:

Sending over AF_PACKET RAW sockets we can sending frames which exceeds MTU size. To handling it correct we need to change things in AF_PACKET which knows on RAW sockets an additional FCS is set by hardware or mac802154 transmit functionality. Signed-off-by:

This patch cleanups needed_headroom, needed_tailroom and hard_header_len fields for wpan and lowpan interfaces. For wpan interfaces the worst case mac header len should be part of needed_headroom, currently this is set as hard_header_len, but hard_header_len should be set to the minimum header length which xmit call assumes and this is the minimum frame length of 802.15.4. The hard_header_len value will check inside send callbacl of AF_PACKET raw sockets. For lowpan interfaces, if fragmentation isn't needed the skb will call dev_hard_header for 802154 layer and queue it afterwards. This happens without new skb allocation, so we need the same headroom and tailroom lengths like 802154 inside 802154 6lowpan layer. At least we assume as minimum header length an ipv6 header size.

The current header_ops callback structure of net device are used mostly from 802.15.4 upper-layers. Because this callback structure is a very generic one, which is also used by e.g. DGRAM AF_PACKET sockets, we can't make this callback structure 802.15.4 specific which is currently is. I saw the smallest "constraint" for calling this callback with dev_hard_header/dev_parse_header by AF_PACKET which assign a 8 byte array for address void pointers. Currently 802.15.4 specific protocols like af802154 and 6LoWPAN will assign the "struct ieee802154_addr" as these parameters which is greater than 8 bytes. The current callback implementation for header_ops.create assumes always a complete "struct ieee802154_addr" which AF_PACKET can't never handled and is greater than 8 bytes. For that reason we introduce now a "generic" create/parse header_ops callback which allows handling with intra-pan extended addresses only. This allows a small use-case with AF_PACKET to send "somehow" a valid dataframe over DGRAM. To keeping the current dev_hard_header behaviour we introduce a similar callback structure "wpan_dev_header_ops" which contains 802.15.4 specific upper-layer header creation functionality, which can be called by wpan_dev_hard_header.

Sometimes upper-layer protocols wants to generate a new mac header by filling "struct ieee802154_hdr" only. These upper-layers sets for the address settings the source and dest fields, but not the fc fields for indicate the source and dest address mode. This patch changes the "ieee802154_hdr_push" function so the fc address fields are set according the source and dest fields of "struct ieee802154_hdr". Signed-off-by:
