All older compiler versions up to gcc-4.9 produce these
harmless warnings:
drivers/net/ieee802154/ca8210.c: In function 'ca8210_skb_tx':
drivers/net/ieee802154/ca8210.c:1947:9: warning: missing braces around initializer [-Wmissing-braces]
This changes the syntax to something that works on all versions
without warnings.

The arrays atusb_chip_data and hulusb_chip_data are local to the source
and do not need to be in global scope, so make them static. Also
remove unnecessary forward declaration of atusb_chip_data.
Cleans up sparse warnings:
symbol 'atusb_chip_data' was not declared. Should it be static?
symbol 'hulusb_chip_data' was not declared. Should it be static?

Geert reported: as fw_ver_maj is unsigned char, gcc 4.1.2 complains:
warning: comparison is always true due to limited range of data type
Besides the warning the old check would also fail for firmware versions
like 1.x with x < 3. These would support frame retries, but the driver
would not enable the feature.

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.
The source code is heavily inspired by the existing atusb
and at86rf2xx drivers.

A device driver must not select the COMMON_CLK subsystem, as that conflicts

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.

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.

Driver code never touches "rstn" signal in atomic context, so there's
no need to implicitly put such restriction on it by using gpio_set_value
to manipulate it. Replace gpio_set_value to gpio_set_value_cansleep to
fix that.
As a an example of where such restriction might be inconvenient,
consider a hardware design where "rstn" is connected to a pin of I2C/SPI
GPIO expander chip.

I expierenced when setting channel while sleep mode it didn't changed
the channel inside the hardware registers. Then I got another report of
an user which has similar issues.
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.

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

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
