| | | | | | | | | | | | | | | | | | | | | | | | | | | This is required since commit 2025172e3280 "spi/bitbang: Use core message pump". spi-bitbang now uses core message pump, so it needs to call spi_master_suspend/ spi_master_resume to start/stop the queue while suspend/resume.

|/ | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* | spi: bitbang: Let spi_bitbang_start() take a reference to masterAxel Lin2013-09-171-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Many drivers that use bitbang library have a leak on probe error paths. This is because once a spi_master_get() call succeeds, we need an additional spi_master_put() call to free the memory. Fix this issue by moving the code taking a reference to master to spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on success. With this change, the caller is responsible for calling spi_bitbang_stop() to decrement the reference and spi_master_put() as counterpart of spi_alloc_master() to prevent a memory leak. So now we have below patten for drivers using bitbang library: probe: spi_alloc_master -> Init reference count to 1 spi_bitbang_start -> Increment reference count remove: spi_bitbang_stop -> Decrement reference count spi_master_put -> Decrement reference count (reference count reaches 0) Fixup all users accordingly.

* spi: Remove HOTPLUG section attributesGrant Likely2012-12-071-3/+3
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Bill Pemberton has done most of the legwork on this series. I've used his script to purge the attributes from the drivers/gpio tree. Reported-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* ARM: S3C24XX: move spi-s3c24xx platdata out of machHeiko Stuebner2012-01-311-1/+1
| | | | | | | | | | spi.h now only contains the definition of the platform data structure for the driver in spi-s3c24xx.c .

* spi: reorganize driversGrant Likely2011-06-061-0/+745
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>
