  • 0848c94fb   mfd: core: Push irqdomain mapping out into devices ... Browse Code »

    Currently the MFD core supports remapping MFD cell interrupts using an
    irqdomain but only if the MFD is being instantiated using device tree
    and only if the device tree bindings use the pattern of registering IPs
    in the device tree with compatible properties. This will be actively
    harmful for drivers which support non-DT platforms and use this pattern
    for their DT bindings as it will mean that the core will silently change
    remapping behaviour and it is also limiting for drivers which don't do
    DT with this particular pattern. There is also a potential fragility if
    there are interrupts not associated with MFD cells and all the cells are
    omitted from the device tree for some reason.

    Instead change the code to take an IRQ domain as an optional argument,
    allowing drivers to take the decision about the parent domain for their
    interrupts. The one current user of this feature is ab8500-core, it has
    the domain lookup pushed out into the driver.

  • b2f0fa828   mfd/asic3: fix asic3_mfd_probe return value ... Browse Code »

    In commit 4f304245b "mfd: Set asic3 DS1WM clock_rate", a possible
    path through asic3_mfd_probe was introduced that would lead to
    an unpredictable return value, if everything succeeds but there
    are pdata->leds is NULL. This was reported correctly by gcc.

    Without this patch, building magician_defconfig results in:

    drivers/mfd/asic3.c: In function 'asic3_mfd_probe':
    drivers/mfd/asic3.c:940:2: warning: 'ret' may be used uninitialized in this function [-Wuninitialized]

  • 2fe372fc2   mfd: Avoid unbalanced asic3 irq wakeup enables/disables ... Browse Code »

    The mfd/asic3 driver does not currently define a irq_set_wake() handler.
    Consequently any attempt to configure the 3 ASIC3 GPIO buttons - RECORD,
    CALENDAR, HOME - as wakeup sources results in Unbalanced IRQ warnings
    when the system is woken from sleep mode:

    WARNING: at kernel/irq/manage.c:520 irq_set_irq_wake+0xc4/0xf8()

  • 4f304245b   mfd: Set asic3 DS1WM clock_rate ... Browse Code »

    The mfd/asic3 driver does not set the ds1wm_driver_data clock_rate field
    before passing the structure to the DS1WM w1 busmaster driver.
    This was not noticed before commit 26a6afb, because ds1wm_find_divisor()
    unintentionally returned the correct divisor when a zero clock_rate was
    passed in. However after that commit DS1WM fails a zero clock_rate:

    ds1wm ds1wm: no suitable divisor for 0Hz clock

    This patch sets the ds1wm_driver_data clock_rate field.

  • 02269ab10   mfd: Fix asic3_gpio_to_irq ... Browse Code »

    Assumption that irq numbers of asic3 gpios start at
    IRQ_BOARD_START is certainly wrong - driver may as well
    use any other base for its irqs (consider for example
    the imaginary case of two ASIC3 chips onboard)

    Furthermore, some platforms even don't have IRQ_BOARD_START
    defined, so driver will fail to build on them:
    -------------------------------------------------------
    drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq':
    drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function)
    drivers/mfd/asic3.c:530: error: (Each undeclared identifier is reported only once
    drivers/mfd/asic3.c:530: error: for each function it appears in.)
    -------------------------------------------------------

    Fix it by using irq_base from driver data.

  • 450b11510   mfd: Add to_irq() member to asic3 gpio_chip structure ... Browse Code »

    The gpio_to_irq() macro is now defined as __gpio_to_irq() instead of IRQ_GPIO().
    The __gpio_to_irq() function returns -ENXIO if the referenced gpio_chip
    structure does not define a to_irq() member.
    This is true of the asic3 gpio_chip structure, and thus calls to gpio_to_irq()
    now fail (for example from the gpio-vbus module).
    This patch defines the to_irq() member in the asic3 gpio_chip structure.

    This sleep should not be required on normal circuitry provided the
    pull-ups on the bus are correctly adapted to the slaves. Unfortunately,
    this is not always the case. The sleep is restored but as a parameter to
    the probe function in the pdata.

  • 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.
