2013-10-16spi: Don't break user-visible strings to multiple source lines in driversJarkko Nikula1-9/+10
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.

2013-10-09spi: spi-bfin5xx: replace platform_driver_probe to support deferred probingWolfram Sang1-1/+2
Subsystems like pinctrl and gpio rightfully make use of deferred probing at core level. Now, deferred drivers won't be retried if they don't have a .probe function specified in the driver struct. Fix this driver to have that, so the devices it supports won't get lost in a deferred probe. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-09-17spi: bfin5xx: convert from legacy pm ops to dev_pm_opsJingoo Han1-11/+13
Instead of using legacy suspend/resume methods, using newer dev_pm_ops structure allows better control over power management. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-08-29spi: use dev_get_platdata()Jingoo Han1-1/+1
Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-05-29spi: convert drivers to use bits_per_word_maskStephen Warren1-16/+5
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.

2013-05-13spi: remove unnecessary platform_set_drvdata()Jingoo Han1-3/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-02-05spi: Remove erroneous __init, __exit and __exit_p() references in driversGrant Likely1-1/+1
Some of the spi driver module remove hooks were annotated with __exit and referenced with __exit_p(). Presumably these were supposed to be __devinit, __devexit and __devexit_p() since __init/__exit for a probe/remove hook has never been correct. They also got missed during the big __devinit/__devexit purge since they didn't match the pattern. Remove then now to be rid of it. v2: purge __init also Reported-by: Arnd Bergmann <arnd@arndb.de> [Arnd set a patch cleaning up one, and then I found more] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2013-02-05spi: remove check for bits_per_word on transfer from low level driverLaxman Dewangan1-2/+1
The spi core make sure that each transfer structure have the proper setting for bits_per_word before calling low level transfer APIs. Hence it is no more require to check again in low level driver for this field whether this is set correct or not. Removing such code from low level driver. The txx9 change also removes a test for bits_per_word set to 0, and forcing it to 8 in that case. This can also be removed now since spi_setup() ensures spi->bits_per_word is not zero. if (!spi->bits_per_word) spi->bits_per_word = 8; Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-12-07spi: Remove HOTPLUG section attributesGrant Likely1-2/+2
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.

2012-04-27spi/spi-bfin5xx: Fix flush of last bit after each spi transferScott Jiang1-1/+4
This patch ensures that the last bit of a transfer gets correctly flushed out of the register. Signed-off-by: Scott Jiang <scott.jiang.linux@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-04-27spi/spi-bfin5xx: fix reversed if condition in interrupt modeScott Jiang1-4/+4
This condition is used to determine 8 bits or 16 and 32 bits transfer. Obviously it is reversed. Signed-off-by: Scott Jiang <scott.jiang.linux@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-04-27spi/bfin_spi: drop bits_per_word from client dataScott Jiang1-1/+0
No other SPI controller has this field, and SPI clients should be setting this up in their own drivers. So drop it from the Blackfin controller to keep people from using it.

2011-10-24spi: irq: Remove IRQF_DISABLEDYong Zhang1-1/+1
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang <yong.zhang0@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-17spi/bfin_spi: uninline fat queue funcsMike Frysinger1-4/+4
There's no need for these queue funcs to be inlined, so drop the markings. This shaves off a few hundred duplicated bytes. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-06-17spi/bfin_spi: use structs for accessing hardware regsMike Frysinger1-124/+84
Rather than hardcoding the register sizes/offsets in this file, use the existing struct in the spi header for reading/writing the hardware. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2011-06-06spi: reorganize driversGrant Likely1-0/+1530
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>
