  • c2cdf6aba   powerpc/macio: Fix probing of macio devices by using the right of match table ... Browse Code »

    Grant patches added an of mach table to struct device_driver. However,
    while he changed the macio device code to use that, he left the match
    table pointer in struct macio_driver and didn't update drivers to use
    the "new" one, thus breaking the probing.

    This completes the change by moving all drivers to setup the "new"
    one, removing all traces of the old one, and while at it (since it
    changes the exact same locations), I also remove two other duplicates
    from struct driver which are the name and owner fields.

  • d58b0c39e   powerpc/macio: Rework hotplug media bay support ... Browse Code »

    The hotplug mediabay has tendrils deep into drivers/ide code
    which makes a libata port reather difficult. In addition it's
    ugly and could be done better.

    This reworks the interface between the mediabay and the rest
    of the world so that:

    - Any macio_driver can now have a mediabay_event callback
    which will be called when that driver sits on a mediabay and
    it's been either plugged or unplugged. The device type is
    passed as an argument. We can now move all the IDE cruft
    into the IDE driver itself

    - A check_media_bay() function can be used to take a peek
    at the type of device currently in the bay if any, a cleaner
    variant of the previous function with the same name.

    - A pair of lock/unlock functions are exposed to allow the
    IDE driver to block the hotplug callbacks during the initial
    setup and probing of the bay in order to avoid nasty race
    conditions.

    - The mediabay code no longer needs to spin on the status
    register of the IDE interface when it detects an IDE device,
    this is done just fine by the IDE code itself

    Overall, less code, simpler, and allows for another driver
    than our old drivers/ide based one.

    mediabay shouldn't include unconditionally so
    remove the superfluous include from mediabay.c (
    will pull in for CONFIG_BLK_DEV_IDE_PMAC=y).

  • 6329db8bd   powerpc: Fix modular build of ide-pmac when mediabay is built in ... Browse Code »

    Now that the powermac IDE host driver can be modular, we need to
    export check_media_bay_by_base() and media_bay_set_ide_infos()
    from drivers/macintosh/mediabay.c for it.

    This fixes the following build error:

    Rework PowerMac media-bay support in such way that instead of
    un/registering the IDE interface we un/register IDE devices:

    * Add ide_port_scan() helper for probing+registerering devices on a port.

    * Rename ide_port_unregister_devices() to __ide_port_unregister_devices().

    * Add ide_port_unregister_devices() helper for unregistering devices on a port.

    * Add 'ide_hwif_t *cd_port' to 'struct media_bay_info', pass 'hwif' instead
    of hwif->index to media_bay_set_ide_infos() and use it to setup 'cd_port'.

    * Use ide_port_unregister_devices() instead of ide_unregister()
    and ide_port_scan() instead of ide_register_hw() in media_bay_step().

    * Unexport ide_register_hw() and make it static.

    v2:
    * Fix build by adding include to .

  • 3a2d5b700   PM: Introduce PM_EVENT_HIBERNATE callback state ... Browse Code »

    During the last step of hibernation in the "platform" mode (with the
    help of ACPI) we use the suspend code, including the devices'
    ->suspend() methods, to prepare the system for entering the ACPI S4
    system sleep state.

    But at least for some devices the operations performed by the
    ->suspend() callback in that case must be different from its operations
    during regular suspend.

    For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
    pass it to the device drivers' ->suspend() methods during the last phase
    of hibernation, so that they can distinguish this case and handle it as
    appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a
    special way and need to handle PM_EVENT_HIBERNATE in the same way.

    These changes are necessary to fix a hibernation regression related
    to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

    This removes statically assigned platform numbers and reworks the
    powerpc platform probe code to use a better mechanism. With this,
    board support files can simply declare a new machine type with a
    macro, and implement a probe() function that uses the flattened
    device-tree to detect if they apply for a given machine.

    We now have a machine_is() macro that replaces the comparisons of
    _machine with the various PLATFORM_* constants. This commit also
    changes various drivers to use the new macro instead of looking at
    _machine.
