* fakelb: rename fakelb_dev_priv to fakelb_phyAlexander Aring2015-05-191-46/+47
| | | | | | | | | | This patch renames fakelb_dev_priv to fakelb_phy. We don't faking devices here, we fake wpan phys. This avoids also confusing with the variable priv, which is used several times in this driver to represent this structure.

* ieee802154: add support for atusb transceiverAlexander Aring2015-05-196-197/+1009
| | | | | | | | | | | | | | | | | | This patch adds support for the atusb transceiver. The current driver supports basic functionality only. Possible further tasks would be to sync functionality with the at86rf230 driver, because the atusb use internally an at86rf231 transceiver. Some of these features need a firmware update like AACK and ARET handling. I did small changes to this driver to work with xmit_async callback and setting of a random extended perm address.

* cfg802154: introduce wpan phy flagsAlexander Aring2015-05-191-2/+7
| | | | | | | | | | | | | | | | | | | | | | | This patch introduce a flag property for the wpan phy structure. The current flag settings in ieee802154_hw are accessable in mac802154 layer only which is okay for flags which indicates MAC handling which are done by phy. For real PHY layer settings like cca mode, transmit power, cca energy detection level. The difference between these flags are that the MAC handling flags are only handled in mac802154/HardMac layer e.g. on an interface up. The phy settings are direct netlink calls from nl802154 into the driver layer and the nl802154 need to have a chance to check if the driver supports this handling before sending to the next layer. We also check now on PHY flags while dumping and setting pib attributes. In comparing with MIB attributes the 802.15.4 gives us an default value which we assume when a transceiver implement less functionality. In case of MIB settings the nl802154 layer doesn't need to check on the ieee802154_hw flags then.

* at86rf230: remove unnecessary spinlockAlexander Aring2015-03-271-9/+0
| | | | | | | | | | | | This spinlock isn't necessary because if we are in TX_ON/TX_ARET_ON state the transceiver can't be interrupted e.g. by receiving a frame when a SHR was detected. In this time the transceiver doesn't leave the TX_ON/TX_ARET_ON state until the tx complete irq change the state into RX_AACK_ON again. This means a receiving interrupt in state TX_ON/TX_ARET_ON can't happen and is_tx is protected by transceiver.

* cc2520: Add support for CC2591 amplifier.Brad Campbell2015-03-181-8/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | The TI CC2521 is an RF power amplifier that is designed to interface with the CC2520. Conveniently, it directly interfaces with the CC2520 and does not require any pins to be connected to a microcontroller/processor. Adding a CC2591 increases the CC2520's range, which is useful for border router and other wall-powered applications. Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs that are connected to the CC2591 to correctly set the CC2591 into TX and RX modes. Further, TI recommends that the CC2520_TXPOWER and CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's performance. These settings are covered in TI Application Note AN065. This patch adds an optional `amplified` field to the cc2520 entry in the device tree. If present, the CC2520 will be configured to operate with a CC2591. The expected pin mapping is: CC2520 GPIO0 --> CC2591 EN CC2520 GPIO5 --> CC2591 PAEN Signed-off-by: Brad Campbell <bradjc5@gmail.com> Acked-by: Varka Bhadram <varkabhadram@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* at86rf230: add support for calibration timeoutAlexander Aring2015-03-141-14/+58
| | | | | | | | | | | | | | | | | | | | This patch adds a handling for calibration if we are 5 minutes in PLL state. I first tried to implement the calibration functionality in TX_ON state via register values CF_START and DCU_START, but this occurs a one second delay at each calibration time. An another solution to start a calibration is to switch from TRX_OFF state into TX_ON, then a calibration is done automatically by transceiver. This method will be used in this patch, after each transmit of a frame we check with jiffies if the PLL is set 5 minutes without doing a TRX_OFF->(TX_ON || RX_AACK_ON) or channel switch. The worst case would be a transceiver in receiving mode only, but this is under normal operation very unlikely.

* at86rf230: add transmit retry supportAlexander Aring2015-03-031-3/+21
| | | | | | | | | | | | | | | | | | This patch introduce a transmit retry handling into at86rf230 transmit path. Current behaviour is to wait the normal receive time if we want to go into STATE_TX_ON when the transceiver is in STATE_BUSY_RX_AACK which indicates that a frame is currently receiving. A non force state change will not interrupt the the receiving state. The current behaviour is that after the normal receive time we will start a force change into STATE_TX_ON. With this patch we do seven retries to go into STATE_TX_ON without forcing. After we hit the AT86RF2XX_MAX_TX_RETRIES we will start the force state change. This is a polling like method to go into STATE_TX_ON in times of maximum receiving time. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
