  • fc6430661   mfd: wm8350-i2c: Make it explicitly non-modular ... Browse Code »

    The Kconfig currently controlling compilation of this code is:

    drivers/mfd/Kconfig:config MFD_WM8350_I2C
    drivers/mfd/Kconfig: bool "Wolfson Microelectronics WM8350 with I2C"

    ...meaning that it currently is not being built as a module by anyone.

    Lets remove the modular code that is essentially orphaned, so that
    when reading the driver there is no doubt it is builtin-only.

    We explicitly disallow a driver unbind, since that doesn't have a
    sensible use case anyway, and it allows us to drop the ".remove"
    code for non-modular drivers.

    Since module_init was not in use by this code, the init ordering
    remains unchanged with this commit.

    We don't replace module.h with init.h since the file already has that.
    But we do delete an unused moduleparam.h

    Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

    We also delete the MODULE_LICENSE tag etc. since all that information
    is already contained at the top of the file in the comments.

    Use the most simple possible transformation on the existing code so keep
    the table sitting around, further patches in this series will delete the
    existing cache code - the main purpose of this patch is to ensure that
    we always have a cache for bisection.

  • fbae3fb15   i2c: Remove all i2c_set_clientdata(client, NULL) in drivers ... Browse Code »

    I2C drivers can use the clientdata-pointer to point to private data. As I2C
    devices are not really unregistered, but merely detached from their driver, it
    used to be the drivers obligation to clear this pointer during remove() or a
    failed probe(). As a couple of drivers forgot to do this, it was agreed that it
    was cleaner if the i2c-core does this clearance when appropriate, as there is
    no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
    This feature was added to the core with commit
    e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

    As there is no need anymore to clear the clientdata-pointer, remove all current
    occurrences in the drivers to simplify the code and prevent confusion.

  • 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.

  • 898d8054e   mfd: Correct WM8350 I2C return code usage ... Browse Code »

    The vendor BSP used for the WM8350 development provided an I2C driver
    which incorrectly returned zero on succesful sends rather than the
    number of transmitted bytes, an error which was then propagated into the
    WM8350 I2C accessors.

  • ebccec0fa   mfd: Add WM8350 interrupt support ... Browse Code »

    The WM8350 has an interrupt line to the CPU which is shared by the
    devices on the CPU. This patch adds support for the interrupt
    controller within the WM8350 which identifies which identifies the
    interrupt cause. In common with other similar chips this is done
    outside the standard interrupt framework due to the need to access
    the interrupt controller over an interrupt-driven bus.

    This code was all originally written by Liam Girdwood with updates for
    submission by me.

    Some functions of the WM8350 require board-specific initialisation on
    startup. Provide a callback to the WM8350 driver in platform data
    for platforms to use to configure the chip. Use of a callback allows
    platforms to control the ordering of initialisation which can be
    important.
