Busware manufactured an USB dongle that is quite similar to the atben and rzusb USB dongles. that are already supported. This patch aims to support the Busware HUL dongle (called hulusb) alongside atusb and rzusb. hulusb is using the at86rf212 transceiver which is specifically designed to support the 700/800/900 MHz wave band.

Add driver source and config for softMAC implementation of Cascoda's CA8210 IEEE 802.15.4 transceiver device. The driver mimics a common PHY-only implementation despite the CA8210 being a hardMAC device which exposes a SAP interface to the fully integrated MAC. The chip is a modem-only device with an integrated processor which runs the 802.15.4 MAC. The chip communicates via full-duplex SPI with additional pins for NIRQ and NRESET. The chip can also output its 16MHz clock to a GPIO with a configurable divider. The driver can be configured to implement a debugfs node that provides access to the SAP-based API to drive mechanisms not currently supported by the standard kernel interface.

2017-03-28net: break include loop netdevice.h, dsa.h, devlink.hAndrew Lunn
There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

I increased the sleep to off state change timing, which is according at86rf233 at maximum 1000 us. After this change I got no similar effects again. I tried another option to wait on AWAKE_END irq, which can be used to wait until the transceiver is awaked. I tested it and the IRQ took 4 seconds after starting state change. I don't believe it takes 4 seconds to go into the TRX_OFF state from SLEEP state. The alternative is to increase the timings which seems to work.

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>
2015-12-11ieee802154-atusb: Delete an unnecessary check before the function call ↵Markus Elfring

This issue was detected by using the Coccinelle software.
