    Pull MFD changes from Samuel Ortiz:
    "MFD bits for the 3.7 merge window.

    As usual we have a few new drivers:

    - TI LP8788
    - TI OMAP USB TLL
    - Maxim MAX8907
    - SMSC ECE1099
    - Dialog Semiconductor DA9055
    - A simpler syscon driver that allow us to get rid of the anatop one.

    Drivers are also gradually getting Device Tree and IRQ domain support.

    The following drivers got DT support:
    - palmas, 88pm860x, tc3589x and twl4030-audio

    And those ones now use the IRQ domain APIs:
    - 88pm860x, tc3589x, db8500_prcmu

    Also some other interesting changes:
    - Intel's ICH LPC now supports Lynx Point
    - TI's twl4030-audio added a GPO child
    - tps6527 enabled its backlight subdevice
    - The twl6030 pwm driver moved to the new PWM subsystem

    And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
    palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."

    Fix up various annoying conflicts: the DT and IRQ domain support came in
    twice and was already in 3.6. And then it was apparently rebased.

    Guys, DON'T REBASE!

    Pull workqueue changes from Tejun Heo:
    "This is workqueue updates for v3.7-rc1. A lot of activities this
    round including considerable API and behavior cleanups.

    * delayed_work combines a timer and a work item. The handling of the
    timer part has always been a bit clunky leading to confusing
    cancelation API with weird corner-case behaviors. delayed_work is
    updated to use new IRQ safe timer and cancelation now works as
    expected.

    * Another deficiency of delayed_work was lack of the counterpart of
    mod_timer() which led to cancel+queue combinations or open-coded
    timer+work usages. mod_delayed_work[_on]() are added.

    These two delayed_work changes make delayed_work provide interface
    and behave like timer which is executed with process context.

    * A work item could be executed concurrently on multiple CPUs, which
    is rather unintuitive and made flush_work() behavior confusing and
    half-broken under certain circumstances. This problem doesn't
    exist for non-reentrant workqueues. While non-reentrancy check
    isn't free, the overhead is incurred only when a work item bounces
    across different CPUs and even in simulated pathological scenario
    the overhead isn't too high.

    All workqueues are made non-reentrant. This removes the
    distinction between flush_[delayed_]work() and
    flush_[delayed_]_work_sync(). The former is now as strong as the
    latter and the specified work item is guaranteed to have finished
    execution of any previous queueing on return.

    * In addition to the various bug fixes, Lai redid and simplified CPU
    hotplug handling significantly.

    * Joonsoo introduced system_highpri_wq and used it during CPU
    hotplug.

    There are two merge commits - one to pull in IRQ safe timer from
    tip/timers/core and the other to pull in CPU hotplug fixes from
    wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."

    Fixed a number of trivial conflicts, but the more interesting conflicts
    were silent ones where the deprecated interfaces had been used by new
    code in the merge window, and thus didn't cause any real data conflicts.

    Tejun pointed out a few of them, I fixed a couple more.

  • 13511def8   regulator: deprecate regulator-compatible DT property ... Browse Code »

    When the bindings for the TPS6586x regulator were being proposed, I
    asserted that DT node naming rules for bus child nodes should also be
    applied to nodes inside the TPS6586x regulator node itself. In other
    words, that each node providing regulator init data should be named
    after the type of object it represented ("regulator") and hence that
    some other property was required to indicate which regulator the node
    described ("regulator-compatible"). In turn this led to multiple nodes
    having the same name, thus requiring node names to use a unit address
    to make them unique, thus requiring reg properties within the nodes and

    However, subsequent discussion indicates that the rules I was asserting
    only applies to standardized bus nodes, and within a device's own node,
    the binding can basically do anything sane that it wants.

    Hence, this change deprecates the register-compatible property, and
    instead uses node names to replace this functionality. This greatly
    simplifies the device tree content, making them smaller and more legible.

    The code is changed such that old device trees continue to work.

    The lp872x_check_dvs_validity() is used for checking DVS platform data.

    Now, this is unnecessary because the default DVS mode is set in this case.

    The lp872x_set_dvs() is used for changing the DVS pin state.
    This function works only when the DVS platform data is defined.
    So don't assume that DVS data is always valid.
    In case the platform data is not defined, the DVS data is set to NULL
    for skipping the DVS pin control.

    DVS selection and GPIO pin number are used for the LP872x DVS pin control.
    For better readability, DVS selection argument is added in lp872x_set_dvs().
