2012-04-13spi/devicetree: Move devicetree support code into spi directoryGrant Likely
The SPI device tree support code isn't shared by any other subsystem. It can be moved into the core drivers/spi directory and the exported symbol can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Rob Herring <rob.herring@calxeda.com>
2012-03-15spi/fsl-espi: Make sure pm is within 2..32Sebastian Andrzej Siewior
The reference manual says that pm has to stay within 2 and 32. So the lowest frequency is 32 and DIV16 set, the highest is 2 and DIV16 unset. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-03-15spi/fsl-espi: make the clock computation easier to readSebastian Andrzej Siewior
The -1 +1 thingy should probably do what DIV_ROUND_UP does. The 4 is 2 the "platform_clock => sysclock" and 2 from the computation part. The 64 is the same 4 times 16. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-10-25drivercore: 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.

2011-06-06spi: 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>
