Ezequiel Garcia 41ab724aac spi/orion: Use module_platform_driver()
This patch reduces and simplifies initalization code by
using module_platform_driver().
With this change it's necessary to remove the __init annotation
to avoid section mismatch warnings.

Grant Likely 2deff8d602 spi: Remove erroneous __init, __exit and __exit_p() references in drivers
Some of the spi driver module remove hooks were annotated with __exit
and referenced with __exit_p(). Presumably these were supposed to be
__devinit, __devexit and __devexit_p() since __init/__exit for a
probe/remove hook has never been correct. They also got missed during
the big __devinit/__devexit purge since they didn't match the pattern.
Remove then now to be rid of it.

v2: purge __init also

Grant Likely fd4a319bc9 spi: Remove HOTPLUG section attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

Jason Gunthorpe b15d5d7004 spi/orion: Add SPI_CHPA and SPI_CPOL support to kirkwood driver.
Support these transfer modes from the SPI layer by setting
the appropriate register bits before doing the transfer.

This was tested on the Marvell kirkwood SOC that uses this driver.

Andrew Lunn ba59a80788 spi: Refactor spi-orion to use SPI framework queue.
Replace the deprecated master->transfer with transfer_one_message()
and allow the SPI subsystem handle all the queuing of messages.

Michael Walle 8ceffa7c4a spi/orion: remove uneeded spi_info
This was formerly used to store the tclk value. This is now discovered
using the clk API, rather than pass it as platform data.

Remove now redundant tclk from SPI platform data. This makes the platform
data empty, so remove it.

Paul Gortmaker d7614de422 spi: Add module.h to implicit users in drivers/spi
We are clipping down the presence of module.h, since it was
everywhere.  If you really need it, you better call it out,

Joe Perches 8e2943c04c spi: Convert uses of struct resource * to resource_size(ptr)
Done via coccinelle scripts like:

@@
struct resource *ptr;

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

Grant Likely ca632f5566 spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.

This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.

v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
      be the predominant pattern for subsystem prefixes.
    - Clean up filenames in Kconfig and header comment blocks
