2018-09-21ieee802154: remove unecessary condition check before debugfs_remove_recursivezhong jiang1-2/+1
debugfs_remove_recursive has taken IS_ERR_OR_NULL into account. So just remove the condition check before debugfs_remove_recursive. Signed-off-by: zhong jiang <zhongjiang@huawei.com> Signed-off-by: Stefan Schmidt <stefan@datenfreihafen.org>

2017-11-29net: ieee802154: adf7242: Rework IRQ and packet handlingMichael Hennerich1-15/+39
* Stop unconditionally polling for RC_STATUS_PHY_RDY at the entry of the threaded IRQ handler. Once IRQ_RX_PKT_RCVD is received we can read immediately the packet from the buffer. However we still need to wait afterwards for RC_STATUS_PHY_RDY, to make sure that the ACK (in case requested) was processed and send out by the Radio Controller, before we issue the next CMD_RC_RX. This significantly reduces the overall time spend in the threaded IRQ handler. * Avoid raise condition between xmit and coincident packet reception, by disabling the IRQ and clearing the IRQ status upon xmit entry. * Introduce helper functions adf7242_clear_irqstat() and adf7242_cmd_rx() Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Stefan Schmidt <stefan@osg.samsung.com>
2017-11-29net: ieee802154: adf7242: Avoid redundant RC_READY pollingMichael Hennerich1-6/+12
READ/WRITE register and packet buffer can be done anytime as long as SPI_READY. Only CMD transactions require RC_READY && SPI_READY. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Stefan Schmidt <stefan@osg.samsung.com>

2016-11-26Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller1-1/+0
udplite conflict is resolved by taking what 'net-next' did which removed the backlog receive method assignment, since it is no longer necessary. Two entries were added to the non-priv ethtool operations switch statement, one in 'net' and one in 'net-next, so simple overlapping changes. Signed-off-by: David S. Miller <davem@davemloft.net>

2016-11-21net: ieee802154: constify ieee802154_ops structuresBhumika Goyal1-1/+1
Declare the structure ieee802154_ops as const as it is only passed as an argument to the function ieee802154_alloc_hw. This argument is of type const struct ieee802154_ops *, so ieee80254_ops structures having this property can be declared as const.

2015-12-11ieee802154/adf7242: Driver for ADF7242 MAC IEEE802154Michael Hennerich1-0/+1285
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>
