2015-09-17spi: omap-uwire: Remove needless bits_per_word and speed_hz testsJarkko Nikula1-3/+4
SPI core validates both bits_per_word and speed_hz transfer parameters and defaults to spi->bits_per_word and spi->max_speed_hz in case these per transfer parameters are not set. This allows to remove two needless tests from uwire_txrx() and uwire_setup_transfer(). Signed-off-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-10-20spi: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-06-24spi: omap-uwire: Fix build errorSachin Kamat1-1/+1
Fixes the following build error introduced by commit b3f6a57506 ("spi: omap-uwire: use devm_ functions"): drivers/spi/spi-omap-uwire.c:465:2: error: implicit declaration of function ‘devm_ioremap’ Since we are including <linux/io.h>, <asm/io.h> is no longer needed.

2014-06-22spi: omap-uwire: use devm_ functionsHimangi Saraogi1-6/+2
This patch introduces the use of devm_clk_get and devm_ioremap instead of the unmanaged interfaces and removes the corresponding free function calls. Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@linaro.org>

spi_bitbang_stop() never fails, so make it return void. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-27spi: omap-uwire: add missing iounmapNishanth Menon1-0/+1
This fixes the following coccicheck warning: linux-2.6/drivers/spi/spi-omap-uwire.c:485:2-8: ERROR: missing iounmap; ioremap on line 471 and execution via conditional on line 481 Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-26spi: omap-uwire: Remove full duplex checkAxel Lin1-4/+0
This driver sets the SPI_MASTER_HALF_DUPLEX flag, so the spi core will check transfers to ensure they are not full duplex. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-03-03spi: omap-uwire: Convert to use bits_per_word_maskAxel Lin1-16/+2
Set bits_per_word_mask so spi core will reject transfers that attempt to use an unsupported bits_per_word value. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-02-12spi: Remove duplicate code to check chip_selectAxel Lin1-6/+0
In spi_add_device(), we have the code to validate spi->chip_select. So remove the duplicate code in various drivers. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-10-09spi: spi-omap-uwire: replace platform_driver_probe to support deferred probingWolfram Sang1-2/+3
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>
2013-05-23spi: use platform_{get,set}_drvdata()Jingoo Han1-2/+2
Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device.

2013-02-05spi: Remove erroneous __init, __exit and __exit_p() references in driversGrant Likely1-3/+3
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>
2012-09-21ARM: OMAP1: Make plat/mux.h omap1 onlyTony Lindgren1-1/+1
We are moving omap2+ to use the device tree based pinctrl-single.c and will be removing the old mux framework. This will remove the omap1 specific parts from plat-omap.

2012-09-13ARM: OMAP1: Move SoC specific headers from plat to mach for omap1Tony Lindgren1-1/+2
There's no need to have these in plat-omap any longer. Note that these could eventually be made local to mach-omap1 instead of being in mach. But to do that, at least various driver access using omap7xxx.h registers needs to be fixed first.

2011-11-01spi: Add module.h to implicit users in drivers/spiPaul Gortmaker1-0/+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>
2011-06-06spi: reorganize driversGrant Likely1-0/+593
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>
