  • 55f0cd3fb   spi: spi-ep93xx: simplify GPIO chip selects ... Browse Code »

    This driver requires a GPIO line to be used for the chip select of
    each SPI device.

    Remove the ep93xx_spi_chip_ops definition from the platform data
    and use the spi core GPIO handling for the chip selects.

    Fix all the ep93xx platforms that use this driver and remove the
    old Documentation.

    Jon Corbet requested this code moved with the last changeset,
    https://lkml.org/lkml/2015/3/1/144,
    but the patch was not applied because it missed the Makefile.
    Moved spidev_test, spidev_fdx and their Makefile infrastructure.

  • 63a29f744   Documentation: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    __devinitconst, and __devexit from the kernel documentation.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

  • ffbbdd213   spi: create a message queueing infrastructure ... Browse Code »
    43

    This rips the message queue in the PL022 driver out and pushes
    it into (optional) common infrastructure. Drivers that want to
    use the message pumping thread will need to define the new
    per-messags transfer methods and leave the deprecated transfer()
    method as NULL.

    Most of the design is described in the documentation changes that
    are included in this patch.

    Since there is a queue that need to be stopped when the system
    is suspending/resuming, two new calls are implemented for the
    device drivers to call in their suspend()/resume() functions:
    spi_master_suspend() and spi_master_resume().

    ChangeLog v1->v2:
    - Remove Kconfig entry and do not make the queue support optional
    at all, instead be more agressive and have it as part of the
    compulsory infrastructure.
    - If the .transfer() method is implemented, delete print a small
    deprecation notice and do not start the transfer pump.
    - Fix a bitrotted comment.
    ChangeLog v2->v3:
    - Fix up a problematic sequence courtesy of Chris Blair.
    - Stop rather than destroy the queue on suspend() courtesy of
    Chris Blair.

    There are numerous broken references to Documentation files (in other

    caused by typo's in the references, and by renames or removals of the

    Fix these broken references, sometimes by dropping the irrelevant text
    they were part of.

    The PXA-SPI driver relies on some files / defines which are arm specific
    and are within the ARM tree. The CE4100 SoC which is x86 has also the
    SPI core.
    This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to
    include/linux where the CE4100 can access them.

    This move got verified by building the following defconfigs:

    The sample application spidev_test.c is using SPI_IOC_MESSAGE ioctl to do
    an SPI transfer. This ioctl returns the number of bytes successfully
    transmitted or a negative error code upon erroneous completion. The
    application however is returning an error if the result of the ioclt if
    the return value is 1. This makes the application to fail upon 1-byte
    length transfers.
