Message-ID: <20110605071725.26517.11573.stgit@ponder>
Date: Sun, 05 Jun 2011 01:18:14 -0600
From: Grant Likely <grant.likely@...retlab.ca>
To: spi-devel-general@...ts.sourceforge.net,
linux-kernel@...r.kernel.org
Subject: [PATCH] spi: reorganize drivers
[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.
Signed-off-by: Grant Likely <grant.likely@...retlab.ca>
