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.

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.

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 Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NWolfram Sang <w.sang@pengutronix.de> Acked-by: NLinus Walleij <linus.walleij@linaro.org>

Some platforms have been known to return NULL from clk_get() if they support only a single struct clk. Whilst tegra doesn't do this, make the drivers consistent with others.
