2012-05-20spi: By default setup spi_masters with 1 chipselect and dynamics bus numberGrant Likely
Trivial simplification. Instead of requiring spi master drivers to always set the bus number (even when a dynamic number is desired), this patch modifies spi_alloc_master() to initialize num_chipselect to 1 (because there will always be at least one CS) and bus_num to -1 for dynamic allocation. This simplifies the code needed to be written for drivers. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-10-24drivercore: Add helper macro for platform_driver boilerplateGrant Likely
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.

2011-06-11spi: Convert uses of struct resource * to resource_size(ptr)Joe Perches
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. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-06spi: reorganize driversGrant Likely
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: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
