Subject[PATCH] spi: reorganize drivers
From
Date
[repost: I had a typo on the spi-devel-general mailing list address]

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.
