2013-03-12spi/pxa2xx-pci: correct the return value check of pcim_iomap_regions()Mika Westerberg
The function returns 0 on success and negative errno in case of failure. Fix this. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-03-12spi: fix return value check in ce4100_spi_probe()Wei Yongjun
In case of error, the function platform_device_register_full() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

2013-01-08spi/pxa2xx: embed the ssp_device to platform dataMika Westerberg
The spi-pxa2xx-pci glue driver had to implement pxa_ssp_request()/free() in order to support the spi-pxa2xx platform driver. Since the ACPI enabled platforms can use the same platform driver we would need to implement pxa_ssp_request()/free() in some central place that can be shared by the ACPI and PCI glue code. Instead of doing that we can make pxa_ssp_request()/free() to be available only when CONFIG_ARCH_PXA is set. On other arches these are being stubbed out in preference to passing the ssp_device from the platform data directly. We also change the SPI bus number to be taken from ssp->port_id instead of platform device id. This way the supporting code that passes the ssp can decide the number (or it can set it to the same as pdev->id).

2013-01-08spi/pxa2xx-pci: switch to use pcim_* interfacesMika Westerberg
Instead of open-coding all the error management in the driver we can take advantage of the pcim_* interfaces that release the resources automatically. We also use platform_device_register_full() to register the platform device because it allows us to create and register the platform device at one go, simplifying the error management. This a preparatory step for getting rid of pxa_ssp_request()/free() which we will do in the next patch.

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.

2012-04-10spi: use module_pci_driverAxel Lin
This patch converts the drivers in drivers/spi/* to use module_pci_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

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>
2011-06-06spi: 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>
