2014-06-18spi: dw: Don't call kfree for memory allocated by devm_kzallocAxel Lin
commit c63f5da00845143de621e991ea186be0829647ee upstream. With devm_kzalloc, the memory is automatically freed when spi_device detach from the bus.

2013-12-31spi: dw: use managed resourcesBaruch Siach
Migrate mmio code and core driver to managed resources to reduce boilerplate error handling code. Also, handle clk_enable() failure while at it, and drop unused dw_spi iolen field. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-10-16spi: Don't break user-visible strings to multiple source lines in driversJarkko Nikula
User-visible strings are more difficult to grep from sources if they are separated to multiple source lines. This is worse than over 80 columns long line code style violation. Fix this by making those to single-line strings or by breaking them between variables. While at there, convert if (printk_ratelimit()) dev_warn() to use dev_warn_ratelimited in spi-pxa2xx.c.

2013-05-29spi: convert drivers to use bits_per_word_maskStephen Warren
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.

2012-12-07spi: Remove HOTPLUG section attributesGrant Likely
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.

2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
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>
2011-10-31spi: Add module.h to implicit users in drivers/spiPaul Gortmaker
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>
2011-09-21spi: spi-dw: fix all sparse warningsH Hartley Sweeten
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.

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>
