* spi: convert drivers to use bits_per_word_maskStephen Warren2013-05-291-22/+4
| | | | | | | | | | Fill in the recently added spi_master.bits_per_word_mask field in as many drivers as possible. Make related cleanups, such as removing any redundant error-checking, or empty setup callbacks.

* 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>
* simple_open: automatically convert to simple_open()Stephen Boyd2012-04-051-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* spi: Add module.h to implicit users in drivers/spiPaul Gortmaker2011-10-311-0/+1
| | | | | | | | We are clipping down the presence of module.h, since it was everywhere. If you really need it, you better call it out, as per this changeset. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* spi: spi-dw: fix all sparse warningsH Hartley Sweeten2011-09-211-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dw_{read,write}[lw] macros produce sparse warnings everytime they are used. The "read" ones cause: warning: cast removes address space of expression warning: incorrect type in argument 1 (different address spaces) expected void const volatile [noderef] <asn:2>*addr got unsigned int *<noident> And the "write" ones: warning: cast removes address space of expression warning: incorrect type in argument 2 (different address spaces) expected void volatile [noderef] <asn:2>*addr got unsigned int *<noident> Fix this by removing struct dw_spi_reg and converting all the register offsets to #defines. Then convert the macros into inlined functions so that proper type checking can occur. While here, also fix the three sparse warnings in spi-dw-mid.c due to the return value of ioremap_nocache being stored in a u32 * not a void __iomem *. With these changes the spi-dw* files all build with no sparse warnings.

* spi: reorganize driversGrant Likely2011-06-061-0/+936
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>
