    Pull ARM SoC cleanups from Arnd Bergmann:
    "A large number of cleanups, all over the platforms. This is dominated
    largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
    others moving code out of arch/arm into more appropriate subsystems.

    The clocksource and irqchip drivers are now abstracted to the point
    where platforms that are already cleaned up do not need to even
    specify the driver they use, it can all get configured from the device
    tree as we do for normal device drivers. The clocksource changes
    basically touch every single platform in the process.

    We further clean up the use of platform specific header files here,
    with the goal of turning more of the platforms over to being
    "multiplatform" enabled, which implies that they cannot expose their
    headers to architecture independent code any more.

    It is expected that no functional changes are part of the cleanup.
    The overall reduction in total code lines is mostly the result of
    removing broken and obsolete code."

    This is w.r.t the changes in PHY library to support adding and getting
    multiple PHYs of the same type. In the new design, the

  • 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.

  • dbc041610   ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+ ... Browse Code »

    As the plat and mach includes need to disappear for single zImage work,
    we need to remove plat/hardware.h.

    Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.

    The old plat/hardware.h already has omap1 only defines, so it gets moved
    to mach/hardware.h for omap1. For omap2+, we use the local soc.h
    that for now just includes the related SoC headers to keep this patch more
    readable.

    Note that the local soc.h still includes plat/cpu.h that can be dealt
    with in later patches. Let's also include plat/serial.h from common.h for
    all the board-*.c files. This allows making the include files local later
    on without patching these files again.

    Note that only minimal changes are done in this patch for the
    drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
    patches are needed to eventually remove cpu_is_omap usage in the drivers.

    Also only minimal changes are done to sound/soc/omap/* to remove the
    unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
    no need to include omap44xx.h.

    While at it, also sort some of the includes in the standard way.

  • 3b972bf06   ARM: OMAP2+: Split omap2_hsmmc_init() to properly support I2C GPIO pins ... Browse Code »

    Otherwise omap_device_build() and omap_mux related functions
    can't be marked as __init when twl is build as a module.

    If a board is using GPIO pins or regulators configured by an
    external chip, such as TWL PMIC on I2C bus, the board must
    mark those MMC controllers as deferred. Additionally both
    omap_hsmmc_init() and omap_hsmmc_late_init() must be called
    by the board.

    For MMC controllers using internal GPIO pins for card
    detect and regulators the slots don't need to be marked
    deferred. In this case calling omap_hsmmc_init() is sufficient.

    Only mark the MMC slots using gpio_cd or gpio_wd as deferred
    as noted by Igor Grinberg .

    Note that this patch does not change the behaviour for
    board-4430sdp.c board-omap4panda.c. These boards wrongly
    rely on the omap_hsmmc.c init function callback to configure
    the PMIC GPIO interrupt lines on external chip. If the PMIC
    interrupt lines are not configured during init, they will
    fail.

  • e74984e46   omap: Set separate timer init functions to avoid cpu_is_omap tests ... Browse Code »

    This is needed for the following patches so we can initialize the
    rest of the hardware timers later on.

    As with the init_irq calls, there's no need to do cpu_is_omap calls
    during the timer init as we only care about the major omap generation.
    This means that we can initialize the sys_timer with the .timer
    entries alone.

    Note that for now we just set stubs for the various sys_timer entries
    that will get populated in a later patch. The following patches will
    also remove the omap_dm_timer_init calls and change the init for the
    rest of the hardware timers to happen with an arch_initcall.

  • 4805734bc   OMAP2+: io: split omap2_init_common_hw() ... Browse Code »

    Split omap2_init_common_hw() into two functions. The first,
    omap2_init_common_infrastructure(), initializes the hwmod code and
    data, the OMAP PM code, and the clock code and data. The second,
    omap2_init_common_devices(), handles any other early device
    initialization that, for whatever reason, has not been or cannot be
    moved to initcalls or early platform devices.

    This patch is required for the hwmod postsetup patch, which allows
    board files to change the state that hwmods should be placed into at
    the conclusion of the hwmod _setup() function. For example, for a
    board whose creators wish to ensure watchdog coverage across the
    entire kernel boot process, code to change the watchdog's postsetup
    state will be added in the board-*.c file between the
    omap2_init_common_infrastructure() and omap2_init_common_devices() function
    calls.
