  • e9c142b0d   regulator: remove locking around regulator_notifier_call_chain() ... Browse Code »

    regulator_notifier_call_chain() doesn't need rdev lock and rdev's
    existence is assumed in the code anyway. Remove the locks from drivers.

  • 9a5ed0bac   regulator: wm831x: Convert to use GPIO descriptors ... Browse Code »

    This converts the Wolfson Micro WM831x DCDC converter to use
    a GPIO descriptor for the GPIO driving the DVS pin.

    There is just one (non-DT) machine in the kernel using this, and
    that is the Wolfson Micro (now Cirrus) Cragganmore 6410 so we
    patch this board to pass a descriptor table and fix up the driver
    accordingly.

  • 119c4f508   regulator: wm831x: Fix notifier mutex lock warning ... Browse Code »

    The mutex for the regulator_dev must be controlled by the caller of
    the regulator_notifier_call_chain(), as described in the comment
    for that function.

    Failure to mutex lock and unlock surrounding the notifier call results
    in a kernel WARN_ON_ONCE() which will dump a backtrace for the
    regulator_notifier_call_chain() when that function call is first made.
    The mutex can be controlled using the regulator_lock/unlock() API.

  • 29454738f   regulator: wm831x: Pass the IRQF_ONESHOT flag ... Browse Code »

    Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests")
    threaded IRQs without a primary handler need to be requested with
    IRQF_ONESHOT, otherwise the request will fail.

    So pass the IRQF_ONESHOT flag in this case.

    The semantic patch that makes this change is available
    in scripts/coccinelle/misc/irqf_oneshot.cocci.

    "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!

  • cd99758ba   mfd: Convert wm831x to irq_domain ... Browse Code »

    The modern idiom is to use irq_domain to allocate interrupts. This is
    useful partly to allow further infrastructure to be based on the domains
    and partly because it makes it much easier to allocate virtual interrupts
    to devices as we don't need to allocate a contiguous range of interrupt
    numbers.

    Convert the wm831x driver over to this infrastructure, using a legacy
    IRQ mapping if an irq_base is specified in platform data and otherwise
    using a linear mapping, always registering the interrupts even if they
    won't ever be used. Only boards which need to use the GPIOs as
    interrupts should need to use an irq_base.

    This means that we can't use the MFD irq_base management since the
    unless we're using an explicit irq_base from platform data we can't rely
    on a linear mapping of interrupts. Instead we need to map things via
    the irq_domain - provide a conveniencem function wm831x_irq() to save a
    small amount of typing when doing so. Looking at this I couldn't clearly
    see anything the MFD core could do to make this nicer.

    Since we're not supporting device tree yet there's no meaningful
    advantage if we don't do this conversion in one, the fact that the
    interrupt resources are used for repeated IP blocks makes accessor
    functions for the irq_domain more trouble to do than they're worth.
