691ee4edd4 spi: spi-sh-msiof: Use of_match_ptr() macro
This eliminates having an #ifdef returning NULL for the case
when OF is disabled.

cf9c86efec spi/sh-msiof: Add device tree parsing to driver
This adds the capability to retrieve setup data from the device tree
node. The usage of platform data is still available.

078b6ead72 spi/sh-msiof: Remove unneeded clock name
clk_get() no longer needs a character string for associating the right
clock as this is done via the device struct now.

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,
as per this changeset.

940ab88962 drivercore: Add helper macro for platform_driver boilerplate
For simple modules that contain a single platform_driver without any
additional setup code then ends up being a block of duplicated
boilerplate.  This patch adds a new macro, module_platform_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

38ada214fa spi: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

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
