  • Pull ARM SoC updates for Marvell mvebu/kirkwood from Olof Johansson:
    "This is a branch with updates for Marvell's mvebu/kirkwood platforms.
    They came in late-ish, and were heavily interdependent such that it
    didn't make sense to split them up across the cross-platform topic
    branches. So here they are (for the second release in a row) in a
    branch on their own."

    Two new platforms have been added, the sunxi platforms (Allwinner A1x

    clps711x has seen a lot of cleanup from Alexander Shiyan, and he's
    also taken on maintainership of the platform.

    converting more platforms to IRQ domains, pinctrl conversion, cleanup
    and general feature enablement across most of the active platforms."

  • This moves the MTU timer driver from arch/arm/plat-nomadik
    to drivers/clocksource and moves the header file to the
    platform_data directory.

    As this moves the last file being compiled to an object out
    of arch/arm/plat-nomadik, we have to "turn off the light"
    and delete the plat-nomadik directory, because it is not
    allowed to have an empty Makefile in a plat-* directory.
    This is probably also a desired side effect of depopulating
    the arch/arm directory of drivers. Luckily we have just
    deleted all the include files prior to this so
    by moving the last one we may delete the directory.

    After this all the Ux500 and Nomadik device drivers live
    outside of the arch/arm hierarchy.

  • Pull ARM soc-specific updates from Olof Johansson:
    "Most notable here is probably the addition of basic support for the
    BCM2835, an SoC used in some of the Roku 2 players as well as the
    much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren.
    It's still early days on mainline support, with just the basics
    working. But it has to start somewhere!

    Beyond that there's some conversions of clock infrastructure on tegra
    to common clock, misc updates for several other platforms, and OMAP
    now has its own bus (under drivers/bus) to manage its devices through.

    This branch adds two new directories outside of arch/arm:
    drivers/irqchip for new irq controllers, and drivers/bus for the above
    OMAP bus. It's expected that some of the other platforms will migrate
    parts of their platforms to those directories over time as well."

  • The System Timer peripheral provides four 32-bit timer channels and a
    single 64-bit free running counter. Each channel has an output compare
    register, which is compared against the 32 least significant bits of the
    free running counter values, and generates an interrupt.

    Timer 3 is used as the Linux timer.

    The BCM2835 also contains an SP804-based timer module. However, it
    apparently has significant differences from the standard SP804 IP block,
    and Broadcom's documentation recommends using the system timer instead.

    This patch was extracted from git://github.com/lp0/linux.git branch
    rpi-split as of 2012/09/08, and modified as follows:

    * s/bcm2708/bcm2835/.
    * Modified device tree vendor prefix.
    * Moved to drivers/clocksource/. This looks like the desired location for
    such code now.
    * Added DT binding docs.
    * Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more.
    * Simplified bcm2835_time_init() to find one matching node and operate on
    it, rather than looping over all matching nodes. This seems more
    consistent with other clocksource code.
    * Simplified bcm2835_time_init() using of_iomap().
    * Renamed struct bcm2835_timer.index to match_mask to better represent its
    purpose.

  • This patch adds support for the ARM generic timers with A64 instructions
    for accessing the timer registers. It uses the physical counter as the
    clock source and the virtual counter as sched_clock.

    The timer frequency can be specified via DT or read from the CNTFRQ_EL0
    register. The physical counter is also accessible from user space
    allowing fast gettimeofday() implementation.

  • The syscore device PM flag is used to mark the devices (belonging to
    a PM domain) that should never be turned off, except for the system
    core (syscore) suspend/hibernation and resume stages. That flag is
    stored in the device's struct pm_subsys_data object whose address is
    available from struct device. However, in some situations it may be
    convenient to set that flag before the device is added to a PM
    domain, so it is better to move it directly to the "power" member of
    struct device. Then, it can be checked by the routines in
    drivers/base/power/runtime.c and drivers/base/power/main.c, which is
    more straightforward.

    This also reduces the number of dev_gpd_data() invocations in the
    generic PM domains framework, so the overhead related to the syscore
    flag is slightly smaller.

  • Pull support for three new arm SoC types from Arnd Bergmann:

    - The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
    made by the mvebu business unit inside of Marvell. Since the same
    group also made the older but similar platforms we call "orion5x",
    "kirkwood", "mv78xx0" and "dove", we plan to move all of them into
    the mach-mvebu directory in the future.

    - socfpga is Altera's platform based on Cortex-A9 cores and a lot of
    FPGA space. This is similar to the Xilinx zynq platform we already
    support. The code is particularly clean, which is helped by the fact
    that the hardware doesn't do much besides the parts that are expected
    to get added in the FPGA.

    - The OMAP subarchitecture gains support for the latest generation, the
    OMAP5 based on the new Cortex-A15 core. Support is rather
    rudimentary for now, but will be extended in the future.

  • The STI hardware is based on a single 48-bit 32kHz
    counter that together with two individual compare
    registers can generate interrupts. There are no
    timer operating modes selectable which means that
    the timer can not clear on match.

    This driver is providing clocksource support for the
    48-bit counter. Clockevents are also supported using
    the same timer in oneshot mode.

  • This platform has been obsoleted and was only available inside of
    ST-Ericsson, no users of this code are left in the world. This
    deletes the core U5500 support entirely in the same manner as the
    obsoleted U8500 silicon was previously deleted.

    The cpu_is_u5500() macros that can read out the CPU ID is left
    until the next kernel cycle, this makes it possible to merge
    deletion of dependent drivers without breakage.

    This also has the upside of removing the mailbox driver which was
    our only driver that was outside the drivers/* hiearchy, now the
    machine directory only handles machines and nothing else.

  • This reverts commit b519508298e0292e1771eecf14aaf67755adc39d.

    The reason for this revert is that making the frequency verification
    preemptible and interruptible is not working reliably. Michaels
    machine failed to use PM-timer with the message:

    PM-Timer running at invalid rate: 113% of normal - aborting.

    That's not a surprise as the frequency verification does rely on
    interrupts being disabled. With a async scheduled thread there is no
    guarantee to achieve the same result. Also some driver might fiddle
    with the CTC channel 2 during the verification period, which makes the
    result even more random and unpredictable.

    This can be solved by using the same mechanism as we use in the
    deferred TSC validation code, but that only will work if we verified a
    working HPET _BEFORE_ trying to do the PM-Timer lazy validation.

    So for now reverting is the safe option.

    This got a fair number of conflicts with the split, but

  • Pull "ARM: device tree work" from Arnd Bergmann:
    "Most of these patches convert code from using static platform data to
    describing the hardware in the device tree. This is only the first
    half of the changes for v3.4 because a lot of patches for this topic
    came in the last week before the merge window.
