2016-01-03ieee802154: cc2520: Check CRC & add promiscuousBrad Campbell
This patch adds checking the "CRC_OK" bit at the end of packets coming from the CC2520 radio. It also adds support for putting the radio in promiscuous mode (in which packets are not dropped if the CRC fails). In promiscuous mode the AUTOCRC flag is cleared so that the driver can pass the received CRC to the monitors. The radio now defaults to frame filtering (checking that the destination and PANID in the incoming packet matches the local node). This matches the other 15.4 radios and is what a user would expect to be the default. Other changes: 1. Adds LQI calculation 2. Makes #defines for relevant bit fields in CC2520 registers Signed-off-by: Brad Campbell <bradjc5@gmail.com> Acked-by: Varka Bhadram <varkabhadram@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-12-11ieee802154/adf7242: Driver for ADF7242 MAC IEEE802154Michael Hennerich
This driver has been sitting in the linux-zigbee[2] repository for a long time. We updated it from time to time and made it available via our github kernel repository. The Linux MAC802.15.4 support has improved a lot since then. Thanks to all! So it’s finally time to upstream this driver. The ADF7242 requires an add-on firmware for the automatic IEEE 802.15.4 operating modes. The firmware file is currently made available on the ADF7242 wiki page here [1] [1] http://wiki.analog.com/resources/tools-software/linux-drivers/networking-mac802154/adf7242 [2] http://sourceforge.net/p/linux-zigbee/kernel/ci/devel/tree/drivers/ieee802154/adf7242.c Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Reviewed-by: Stefan Schmidt <stefan@osg.samsung.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2015-09-22mrf24j40: change irq trigger type behaviourAlexander Aring
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.

2015-09-22at86rf230: support edge triggered irqAlexander Aring
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: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2015-09-17at86rf230: change trac status check behaviourAlexander Aring
When transmit is done, indicated by trx_end irq, we do first a force state change to TX_ON and then checking the trac status, if the trac status is unequal zero we do a state change to TRX_OFF. This patch changes to the following behaviour, we first check on trac status after trx_end occurs and then doing a normal change to TX_ON without do the state change to TRX_OFF when trac status is unequal zero. The reasons are that the datasheet doesn't described when the trac status register is cleared, we should doing to evaluate the trac status at first. The reason to remove the TRX_OFF change if the trac status is unequal to zero and it was force is the following paragraph inside The at86rf2xx datasheets: "Using FORCE_PLL_ON to interrupt an TX_ARET transaction, it is recommended to check register bits [7:5] of register address 0x32 for value 0. If this value is different, TRX_CMD sequence FORCE_TRX_OFF shall be used immediately followed by TRX_CMD sequence PLL_ON. This performs a state transition to PLL_ON." The meaning is here "to interrupt an TX_ARET transaction" in case of trx_end interrupt the "TX_ARET transaction" is already done and we don't interrupt the "TX_ARET transaction" by doing the change to TX_ON (PLL_ON) here. Additional I changed the force change to normal TX_ON which seems to work here.
