  • e102dc7a5   rtc: mv: reset date if after year 2038 ... Browse Code »

    Dates after January, 19th 2038 are badly handled by userspace due to
    the time being stored on 32 bits. This causes issues on some Marvell
    platform on which the RTC is initialized by default to a date that's
    beyond 2038, causing a really weird behavior of the RTC.

    In order to avoid that, reset the date to a sane value if the RTC is
    beyond 2038.

  • 7c1d69ee1   rtc: simplify devm_request_mem_region/devm_ioremap ... Browse Code »

    Convert the composition of devm_request_mem_region and devm_ioremap to a
    single call to devm_ioremap_resource. The associated call to
    platform_get_resource is also simplified and moved next to the new call
    to devm_ioremap_resource.

    This was done using a combination of the semantic patches
    devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in
    the scripts/coccinelle/api directory.

    In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed.

    In rtc-ds1511.c the size field of the local structure is not useful any
    more, and is deleted.

  • 89c58c198   rtc: rtc-mv: Add support for clk to avoid lockups ... Browse Code »

    The Marvell RTC on Kirkwood makes use of the runit clock. Ensure the
    driver clk_prepare_enable() this clock, otherwise there is a danger
    the SoC will lockup when accessing RTC registers with the clock
    disabled.

  • 5a167f454   Drivers: rtc: 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 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.

    Pull "ARM: More device tree support updates" from Olof Johansson:
    "This branch contains a number of updates for device tree support on
    several ARM platforms, in particular:

    * AT91 continues the device tree conversion adding support for a
    number of on-chip drivers and other functionality
    * ux500 adds probing of some of the core SoC blocks through device
    tree
    * Initial device tree support for ST SPEAr600 platforms
    * kirkwood continues the conversion to device-tree probing"

    Manually merge arch/arm/mach-ux500/Kconfig due to MACH_U8500 rename, and
    drivers/usb/gadget/at91_udc.c due to header file include cleanups.

    Also do an "evil merge" for the MACH_U8500 config option rename that the
    affected RMI4 touchscreen driver in staging. It's called MACH_MOP500
    now, and it was missed during previous merges.

  • 2f6e5f945   drivers/rtc: remove IRQF_DISABLED ... Browse Code »

    Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts
    disabled") we run all interrupt handlers with interrupts disabled and we
    even check and yell when an interrupt handler returns with interrupts
    enabled - see commit b738a50a2026 ("genirq: warn when handler enables
    interrupts").

    So now this flag is a NOOP and can be removed.

  • 16380c153   RTC: Convert rtc drivers to use the alarm_irq_enable method ... Browse Code »

    Some rtc drivers use the ioctl method instead of the alarm_irq_enable
    method for enabling alarm interupts. With the new virtualized RTC
    rework, its important for drivers to use the alarm_irq_enable instead.

    This patch converts the drivers that use the AIE ioctl method to
    use the alarm_irq_enable method. Other ioctl cmds are left untouched.

    I have not been able to test or even compile most of these drivers.
    Any help to make sure this change is correct would be appreciated!

  • 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.

    This patch adds the Alarm support, this mode enabled when adding
    IORESOURCE_IRQ to the platform device resources.

    The patch also enables the wakeup mode, so the wakealarm sysfs file (under
    /sys/class/rtc/rtcX/) can be used to configure the alarm clock.
