  • bd0b9ac40   genirq: Remove irq argument from irq flow handlers ... Browse Code »

    Most interrupt flow handlers do not use the irq argument. Those few
    which use it can retrieve the irq number from the irq descriptor.

    Remove the argument.

    Search and replace was done with coccinelle and some extra helper
    scripts around it. Thanks to Julia for her help!

  • e8d36d5db   ARM: kill off set_irq_flags usage ... Browse Code »

    set_irq_flags is ARM specific with custom flags which have genirq
    equivalents. Convert drivers to use the genirq interfaces directly, so we
    can kill off set_irq_flags. The translation of flags is as follows:

    IRQF_VALID -> !IRQ_NOREQUEST
    IRQF_PROBE -> !IRQ_NOPROBE
    IRQF_NOAUTOEN -> IRQ_NOAUTOEN

    For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    and setting IRQ_NOREQUEST already, so there is no need to do this in
    .map() functions and we can simply remove the set_irq_flags calls. Some
    users also modify IRQ_NOPROBE and this has been maintained although it
    is not clear that is really needed. There appears to be a great deal of
    blind copy and paste of this code.

  • a927ef895   ARM: pxa: fix dm9000 platform data regression ... Browse Code »

    Since dm9000 driver added support for a vcc regulator, platform data
    based platforms have their ethernet broken, as the regulator claiming
    returns -EPROBE_DEFER and prevents dm9000 loading.

    This patch fixes this for all pxa boards using dm9000, by using the
    specific regulator_has_full_constraints() function.

    This was discovered and tested on the cm-x300 board.

    Pull ARM SoC cleanups from Olof Johansson:
    "This branch contains code cleanups, moves and removals for 3.12.

    There's a large number of various cleanups, and a nice net removal of
    13500 lines of code.

    Highlights worth mentioning are:

    - A series of patches from Stephen Boyd removing the ARM local timer
    API.
    - Move of Qualcomm MSM IOMMU code to drivers/iommu.
    - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM
    driver and switching over to the drivers/pwm one.
    - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).

    There's also a move of a header file out of include/linux/i2c/ to
    platform_data, where it really belongs. It touches mostly ARM
    platform code for include changes so we took it through our tree"

  • 6bb27d734   ARM: delete struct sys_timer ... Browse Code »

    Now that the only field in struct sys_timer is .init, delete the struct,
    and replace the machine descriptor .timer field with the initialization
    function itself.

    This will enable moving timer drivers into drivers/clocksource without
    having to place a public prototype of each struct sys_timer object into
    include/linux; the intent is to create a single of_clocksource_init()
    function that determines which timer driver to initialize by scanning
    the device dtree, much like the proposed irqchip_init() at:
    http://www.spinics.net/lists/arm-kernel/msg203686.html

    Includes mach-omap2 fixes from Igor Grinberg.

    This tries to clear up the confusion between integers and iomem pointers
    in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
    values, in order to let the Linux type checking work correctly. This
    patch moves the cast to __iomem as far back as possible, to the place
    where the MMIO virtual address windows are defined.
