  • d89299428   Drivers: mtd: 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, and __devexit
    from these drivers.

    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.

    of_device is just an alias for platform_device, so remove it entirely. Also
    replace to_of_device() with to_platform_device() and update comment blocks.

    This patch was initially generated from the following semantic patch, and then

  • 4018294b5   of: Remove duplicate fields from of_platform_driver ... Browse Code »

    .name, .match_table and .owner are duplicated in both of_platform_driver
    and device_driver. This patch is a removes the extra copies from struct
    of_platform_driver and converts all users to the device_driver members.

    This patch is a pretty mechanical change. The usage model doesn't change
    and if any drivers have been missed, or if anything has been fixed up
    incorrectly, then it will fail with a compile time error, and the fixup
    will be trivial. This patch looks big and scary because it touches so
    many files, but it should be pretty safe.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • ade92a636   [MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delays ... Browse Code »

    The NAND flash on the TQM8548_BE modules requires a short delay after
    running the UPM pattern. The TQM8548_BE requires a further short delay
    after writing out a buffer. Normally the R/B pin should be checked, but
    it's not connected on the TQM8548_BE. The existing driver uses similar
    fixed delay points. To manage these extra delays in a more general way,
    I introduced the "fsl,ump-wait-flags" property allowing the board-
    specific driver to specify various types of extra delay.

    This patch extends the FSL UPM NAND driver from Anton Vorontsov to
    support hardware which does not have the R/B pin of the NAND chip
    connected, like the TQM8548 module:

    - The OF_GPIO dependency has been removed from the Kconfig option
    because GPIO is not needed. The relevant gpio_* function are then
    stubbed out in .

    - It re-introduces the chip-delay property to define an appropriate
    maximum delay time (tR) required for read operations. The binding
    will be documented in a separate patch.

    - Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't

    didn't need fsl,wait-pattern, but I assume this was the exception
    that proves the rule;
    - Get rid of chip-delay. Today there are no users for this, and if
    anyone really need this they should push the OF bindings beforehand;
    - Now flash chips should be child nodes of the FSL UPM NAND controller;
    - Implement OF partition parsing.
