  • power management changes for omap and imx

    A significant part of the changes for these two platforms went into

  • New feature development

    This adds support for new features, and contains stuff from most
    platforms. A number of these patches could have fit into other
    branches, too, but were small enough not to cause too much
    confusion here.

  • Device tree conversions for samsung and tegra

    Both platforms had some initial device tree support, but this adds

    changes.

    Lots of relatively simple conflicts between the board

    the resolution from the samsung/cleanup tree, so we
    don't get conflicting merges.

  • Before we enable the MMU, we must ensure that the TTBR registers contain
    sane values. After the MMU has been enabled, we jump to the *virtual*
    address of the following function, so we also need to ensure that the
    SCTLR write has taken effect.

    This patch adds ISB instructions around the SCTLR write to ensure the
    visibility of the above.

  • Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
    interrupt definitions in the dts files according to
    Documentation/devicetree/bindings/arm/gic.txt

    v3 (swarren):
    * Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
    - Even with a dummy replacement if !CONFIG_OF, the reference from
    tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
    - It's plausible that tegra_dt_irq_match[] may need to contain more
    entries in the future, and defining what they are seems more suitable
    for board-dt.c than irq.c
    v2 (swarren):
    * Removed some stale GIC init code from board-dt.c
    * Undid some accidental 0x -> 0x0 search/replace.
