    This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That
    commit causes two kinds of breakage; it breaks registration of AMBA
    devices when one of the parent nodes already contains overlapping
    resource regions, and it breaks calls to request_region() by device
    drivers in certain conditions where there are overlapping memory
    regions. Both of these problems can probably be fixed, but it is better
    to back out the commit and get a proper fix designed before trying again.

  • d6d3c4e65   OF: convert devtree lock from rw_lock to raw spinlock ... Browse Code »

    With the locking cleanup in place (from "OF: Fixup resursive
    locking code paths"), we can now do the conversion from the
    rw_lock to a raw spinlock as required for preempt-rt.

    The previous cleanup and this conversion were originally
    separate since they predated when mainline got raw spinlock (in
    commit c2f21ce2e31286a "locking: Implement new raw_spinlock").

    So, at that point in time, the cleanup was considered plausible
    for mainline, but not this conversion. In any case, we've kept
    them separate as it makes for easier review and better bisection.

  • aac73f345   of: use platform_device_add ... Browse Code »

    This allows platform_device_add a chance to call insert_resource on all
    of the resources from OF. At a minimum this fills in proc/iomem and
    presumably makes resource tracking and conflict detection work better.
    However, it has the side effect of moving all OF generated platform
    devices from /sys/devices to /sys/devices/platform/. It /shouldn't/
    break userspace because userspace is not supposed to depend on the full
    path (because userspace always does what it is supposed to, right?).

    This may cause breakage if either:
    1) any two nodes in a given device tree have overlapping & staggered
    regions (ie. 0x80..0xbf and 0xa0..0xdf; where one is not contained
    within the other). In this case one of the devices will fail to
    register and an exception will be needed in platform_device_add() to
    complain but not fail.
    2) any device calls request_mem_region() on a region larger than
    specified in the device tree. In this case the device node may be
    wrong, or the driver is overreaching. In either case I'd like to know
    about any problems and fix them.

    Please test. Despite the above, I'm still fairly confident that this
    patch is in good shape. I'd like to put it into linux-next, but would
    appreciate some bench testing from others before I do; particularly on
    PowerPC machines.

  • ced4eec90   of: Output devicetree alias names in uevent ... Browse Code »

    In some situations, userspace may want to resolve a
    device by function and logical number (ie, "serial0")
    rather than by the base address or full device path. Being
    able to resolve a device by alias frees userspace from the
    burden of otherwise having to maintain a mapping between
    device addresses and their logical assignments on each
    platform when multiple instances of the same hardware block
    are present in the system.

    Although the uevent device attribute contains devicetree
    compatible information and the full device path, the uevent
    does not list the alises that may have been defined for the
    device.

  • 28d0e36bf   OF: Fixup resursive locking code paths ... Browse Code »

    There is no real reason to use a rwlock for devtree_lock. It even
    could be a mutex, but unfortunately it's locked from cpu hotplug
    paths which can't schedule :(

    So it needs to become a raw lock on rt as well. The devtree_lock would
    be the only user of a raw_rw_lock, so we are better off cleaning up the
    recursive locking paths which allows us to convert devtree_lock to a
    read_lock.

    Here we do the standard thing of introducing __foo() as the "raw"
    version of foo(), so that we can take better control of the locking.
    The "raw" versions are not exported and are for internal use within
    the file itself.

    The of_find_matching_node_and_match() function incorrectly sets the matched
    entry to 'matches' when the compatible value of a node matches one of the
    possible values. This results in incorrectly selecting the the first entry in
    the 'matches' list as the matched entry. Fix this by noting down the result of
    the call to of_match_node() and setting that as the matched entry.

  • f9a8f83b0   net: phy: remove flags argument from phy_{attach, connect, connect_direct} ... Browse Code »
    26

    The flags argument of the phy_{attach,connect,connect_direct} functions
    is then used to assign a struct phy_device dev_flags with its value.
    All callers but the tg3 driver pass the flag 0, which results in the
    underlying PHY drivers in drivers/net/phy/ not being able to actually
    use any of the flags they would set in dev_flags. This patch gets rid of
    the flags argument, and passes phydev->dev_flags to the internal PHY
    library call phy_attach_direct() such that drivers which actually modify
    a phy device dev_flags get the value preserved for use by the underlying
    phy driver.

    The following pattern of code is tempting:

    for_each_matching_node(np, table) {
    match = of_match_node(table, np);

    However, this results in iterating over table twice; the second time
    inside of_match_node(). The implementation of for_each_matching_node()
    already found the match, so this is redundant. Invent new function
    of_find_matching_node_and_match() and macro
    for_each_matching_node_and_match() to remove the double iteration,
    thus transforming the above code to:

    for_each_matching_node_and_match(np, table, &match)

    The of_prop_reconfig property contains a pointer to the node containing the
