Linus Torvalds 0082c16e3a spi: Updates for 3.6
Since Grant is even more specacularly busy than usual for the time being
 I've been collecting SPI patches for him for this release - probably
 things will revert back to Grant before the next release.  There's
 nothing too exciting here, mostly it's simple driver specific stuff:
 
 - Add spi: to the modaliases of SPI devices to provide namespacing.
 - A driver for AD-FMCOMMS1-EBZ.
 - DT binding for Orion.
 - Fixes and cleanups for i.MX, PL0022, OMAP and bitbang drivers.
 
 There may be a few more fixes I've missed, people keep sending me new
 things.

Laxman Dewangan 619ac8d3e5 spi: tegra: use dmaengine based dma driver
Use the dmaengine based Tegra APB DMA driver for
data transfer between SPI FIFO and memory in
place of legacy Tegra APB DMA.

The new driver is selected if legacy driver is not
selected and new DMA driver is enabled through config
file.

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.

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
