A device driver must not select the COMMON_CLK subsystem, as that conflicts
with platforms that provide a legacy implementation of the clk API:
drivers/clk/clk.o: In function `clk_enable':
clk.c:(.text.clk_enable+0x0): multiple definition of `clk_enable'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_enable+0x0): first defined here
drivers/clk/clk.o: In function `clk_round_rate':
clk.c:(.text.clk_round_rate+0x0): multiple definition of `clk_round_rate'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_round_rate+0x0): first defined here
drivers/clk/clk.o: In function `clk_get_parent':
clk.c:(.text.clk_get_parent+0x0): multiple definition of `clk_get_parent'
arch/arm/mach-sa1100/clock.o:clock.c:(.text.clk_get_parent+0x0): first defined here
drivers/clk/clk.o: In function `clk_get_rate':
clk.c:(.text.clk_get_rate+0x0): multiple definition of `clk_get_rate'
This changes the 'select' into 'depends on', as all other similar drivers do.

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.

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]

This patch introduce regmap support for short and long address space of
mrf24j40. It's only possible to use regmap_read/write/update_bits for
long address range. This is because I added lowlevel bus operation
because the write operation need to set the 12th bit to mark a register
write, but regmap only supports to set bits for register write access in
the first byte. We use other regmap register functions than
read/write/update_bits, so this should be fine.

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.

The rf233 and rf231 are sufficiently similar that we can treat
rf233 like rf231.
rf233 is missing some features that rf231 has, but we don't currently
make use of them so there's nothing to handle differently yet.
Should we add support in the future for rf231 *_NOCLK or SLEEP states,
or PAD_IO drive strength, exceptions will need to be made for rf233.

The IEEE 802.15.4 standard represents a networking protocol. I don't
exactly know why drivers for this protocol are stored into the root
'driver' folder, but better will be to store them with other
networking stuff. Currently there are only 3 drivers available for
IEEE 802.15.4 stack, so lets do it now with the smallest overhead.
