Florian Vaussard b18ec27c65 can: sja1000: of: add reg-io-width property for 8, 16 and 32-bit register access
Add the 'reg-io-width' property for 8, 16 and 32-bit access, like
what is currently done with IORESOURCE_MEM_{8,16,32}BIT for non-OF
boot.

Jeff Kirsher 05780d9808 can: Fix FSF address in file headers
Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL <http://www.gnu.org/licenses/> so that we do not have to keep
updating the header comments anytime the address changes.

Jingoo Han ecd78d9753 can: sja1000: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

Jingoo Han 00e4bbc8cd net: can: use platform_{get,set}_drvdata()
Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Sven Schmitt da3d50ef30 can: sja1000_platform: fix wrong flag IRQF_SHARED for interrupt sharing
The sja1000 platform driver wrongly assumes that a shared IRQ is indicated
with the IRQF_SHARED flag in irq resource flags. This patch changes the
driver to handle the correct flag IORESOURCE_IRQ_SHAREABLE instead.

There are no mainline users of the platform driver which wrongly make use
of IRQF_SHARED.

Axel Lin 871d337255 net/can: convert drivers/net/can/* to use module_platform_driver()
This patch converts the drivers in drivers/net/can/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Wolfgang Grandegger 56e6943b90 can: sja1000 platform data fixes
The member "clock" of struct "sja1000_platform_data" is documented as
"CAN bus oscillator frequency in Hz" but it's actually used as the CAN
clock frequency, which is half of it. To avoid further confusion, this
patch fixes it by renaming the member to "osc_freq". That way, also
non mainline users will notice the change. The platform code for the
relevant boards is updated accordingly. Furthermore, pre-defined
values are now used for the members "ocr" and "cdr".

Hans J. Koch 829e001543 Fix some #includes in CAN drivers (rebased for net-next-2.6)
In the current implementation, CAN drivers need to #include <linux/can.h>
_before_ they #include <linux/can/dev.h>, which is both ugly and
unnecessary.

Fix this by including <linux/can.h> in <linux/can/dev.h> and remove the
#include <linux/can.h> lines from drivers.

Wolfgang Grandegger 255a915431 can: sja1000: stop misusing member base_addr of struct net_device
As discussed on the netdev mailing list, the member "base_addr" of
"struct net_device" should not be (mis)used to store the virtual
address to the SJA1000 register area. According to David Miller,
it's only use is to allow ISA and similar primitive bus devices to
have their I/O ports changed via ifconfig. The virtual address is
now stored in the private data structure of the SJA1000 device and
the callback functions use "struct sja1000_priv" instead of the
unneeded "struct net_device".
