Andrew Lunn ba59a80788 spi: Refactor spi-orion to use SPI framework queue.
Replace the deprecated master->transfer with transfer_one_message()
and allow the SPI subsystem handle all the queuing of messages.

Michael Walle 8ceffa7c4a spi/orion: remove uneeded spi_info
This was formerly used to store the tclk value. This is now discovered
using the clk API, rather than pass it as platform data.

Andrew Lunn 4574b88669 ARM: Orion: SPI: Add clk/clkdev support.
Remove now redundant tclk from SPI platform data. This makes the platform
data empty, so remove it.

Paul Gortmaker 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.

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
