Jingoo Han 8074cf063e spi: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

Axel Lin 044d0bb620 spi: nuc900: Fix mode_bits setting
The code in nuc900_slave_select() supports handling SPI_CS_HIGH.
Thus set SPI_CS_HIGH bit in master->mode_bits to make it work.
Otherwise, spi_setup() will return unsupported mode bits error message if
SPI_CS_HIGH is set in the mode field of struct spi_device.

Mark Brown 30af9b558a spi/bitbang: Drop empty setup() functions
Now that the bitbang core does not require a setup() function we can
drop the check in the altera, nuc900 and xilinx drivers.

Stephen Warren 103ccee4ef spi: revert master->setup function removal for altera and nuc900
Commit 24778be "spi: convert drivers to use bits_per_word_mask" removed
what appeared to be redundant code from many drivers. However, it
appears that in the spi-bitbang case, these functions are required by
the spi-bitbang core, even if they don't do anything. Restore them.

For 3.12, the spi-bitbang core should be adjusted not to require these
callbacks to exist if they don't need to do anything.

This is the equivalent of Michal Simek's patch "spi/xilinx: Revert
master->setup function removal", applied to other affected drivers.

Fill in the recently added spi_master.bits_per_word_mask field in as
many drivers as possible. Make related cleanups, such as removing any
redundant error-checking, or empty setup callbacks.

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.

Arnd Bergmann 54ecf4f056 ARM: w90x900: move platform_data definitions
Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.

This moves such data out of the w90x900 include directories

Grant Likely 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.

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
