This patch change the handling of transmit power level from dbm to mbm. This prepares to handle floating point transmit power levels values. The old netlink 802.15.4 will convert the dbm value to mbm for handling backward compatibility.

This patch change the transmit power from s8 to s32. This prepares to store a mbm value instead dbm inside the transmit power variable. The old interface keep the a s8 dbm value, which should be backward compatibility when assign s8 to s32.

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.

This patch fix an issue when at86rf230_read_subreg was successful. The function at86rf230_read_subreg will directly call regmap_read which returns zero on successful. Nobody figured out issues yet because it was only necessary to evaluate dvdd state while probing. This could make trouble because the stack variable could have an random value. The function is also used by reset the irq line before requesting irq, but the value isn't evaluated afterwards.

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.

In the most cases the spi messages has a length of two. Currently we always set the the len field to two before transmit a spi message. In cases for read out/write in the frame buffer we need another len. This patch use trx len two as default. For the frame buffer cases we restore the trx len to two on success and failure. This will reduce the len setting of two when it's already two. Signed-off-by: NAlexander Aring <alex.aring@gmail.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

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: NAlexander Aring <alex.aring@gmail.com> Signed-off-by: NMarcel Holtmann <marcel@holtmann.org>

While testing I experience a deadlock while using the at86rf233 on a raspberry pi. The reason was an edge triggered gpio irq because the irq triggered while irq was disabled. This issue doesn't happend on a level triggered irq because the irq will hit after calling enable_irq. This patch adds a warning that it's not recommended to use a edge-triggered irq type.
