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.

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.

5b7bea9f12 spi/tegra: fix compilation error in spi-tegra.c 
Add #include <linux/module.h> to spi-tegra.c to fix a compilation error
after the removal of module.h from device.h (in patch: "include: replace
linux/module.h with "struct module" wherever possible").

22032c7774 spi/tegra: Use engineering names in DT compatible property 
Engineering names are more stable than marketing names. Hence, use them
for Device Tree compatible properties instead.

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.

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
