  • 687b81d08   i2c: move OF helpers into the core ... Browse Code »

    I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
    that it is much cleaner to have this in the core. This also removes a
    circular dependency between the helpers and the core, and so we can
    finally register child nodes in the core instead of doing this manually
    in each driver. So, fix the drivers and documentation, too.

  • 55827f4aa   i2c: Remove unneeded xxx_set_drvdata(..., NULL) calls ... Browse Code »

    There is simply no reason to be manually setting the private driver
    data to NULL in the remove/fail to probe cases. This is just extra
    cruft code that can be removed.

    A few notes:
    * Nothing relies on drvdata being set to NULL.
    * The __device_release_driver() function eventually calls
    dev_set_drvdata(dev, NULL) anyway, so there's no need to do it
    twice.
    * I verified that there were no cases where xxx_get_drvdata() was
    being called in these drivers and checking for / relying on the NULL
    return value.

    This could be cleaned up kernel-wide but for now just take the baby
    step and remove from the i2c subsystem.

  • 44454baa7   i2c: Dynamically assign adapter id if it wasn't explictly specified ... Browse Code »

    Commit 488bf314b ("i2c: Allow i2c_add_numbered_adapter() to assign a
    bus id") reworked i2c_add_numbered_adapter() to call i2c_add_adapter()
    if requested bus was -1.

    This allows to simplify driver's initialization procedure by using
    just one function for static and dynamic adapter id registration.

    This patch updates few more drivers (missed out in original patch)
    to use this functionality.

  • 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.

  • c6ffddea3   i2c: Use resource_size macro ... Browse Code »

    This replace all instances in the i2c busses tree of
    res->end - res->start + 1 with the handy macro resource_size(res)
    from ioport.h (coming in from platform_device.h).

    This was created with a simple
    sed -i -e 's/\([a-z]*\)->end *- *[a-z]*->start *+ *1/resource_size(\1)/g'

    Then manually replacing the PXA redefiniton of the same kind
    of macro manually. Recompiled some ARM defconfigs I could find to
    make a rough test so it shouldn't break anything, though I
    couldn't see exactly which configs you need for all the drivers.
