  • eb1f29306   Driver for the Atmel on-chip SSC on AT32AP and AT91 ... Browse Code »

    The Synchronous Serial Controller (SSC) on Atmel microprocessors are
    capable of tranceiving many frame based protocols, like I2S. Tested on the
    AT32AP7000/ATSTK1000.

    This driver is used in the ALSA sound driver for the AT73C213 external DAC
    on the ATSTK1000 development board for AVR32. This sound driver will be
    submitted soon.

    Hardware documentation can be found in the AT32AP7000 data sheet, which can
    be downloaded from
    http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

  • 7eff2e7a8   Driver core: change add_uevent_var to use a struct ... Browse Code »

    This changes the uevent buffer functions to use a struct instead of a
    long list of parameters. It does no longer require the caller to do the
    proper buffer termination and size accounting, which is currently wrong
    in some places. It fixes a known bug where parts of the uevent
    environment are overwritten because of wrong index calculations.

    Many thanks to Mathieu Desnoyers for finding bugs and improving the
    error handling.

  • 1855256c4   drivers/firmware: const-ify DMI API and internals ... Browse Code »

    Three main sets of changes:

    1) dmi_get_system_info() return value should have been marked const,
    since callers should not be changing that data.

    2) const-ify DMI internals, since DMI firmware tables should,
    whenever possible, be marked const to ensure we never ever write to
    that data area.

    3) const-ify DMI API, to enable marking tables const where possible
    in low-level drivers.

    And if we're really lucky, this might enable some additional
    optimizations on the part of the compiler.

    The bulk of the changes are #2 and #3, which are interrelated. #1 could
    have been a separate patch, but it was so small compared to the others,
    it was easier to roll it into this changeset.

  • ff80f1370   ACPI: thinkpad-acpi: revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED option ... Browse Code »

    Revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED Kconfig option because
    it would create a legacy we don't want to support.

    CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is
    now moot with the addition of the netlink ACPI event report interface to
    the ACPI core.

    Now that ACPI core can send events over netlink, we can use a different
    strategy to keep backwards compatibility with older userspace, without the
    need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games. And it arrived
    before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline
    kernel, even, which is Good.

    This patch is in sync with some changes to thinkpad-acpi backports, that
    will keep things sane for userspace across different combinations of kernel
    versions, thinkpad-acpi backports (or the lack thereof), and userspace
    capabilities:

    Unless a module parameter is used, thinkpad-acpi will now behave in such a
    way that it will work well (by default) with userspace that still uses only
    the old ACPI procfs event interface and doesn't care for thinkpad-acpi
    input devices.

    It will also always work well with userspace that has been updated to use
    both the thinkpad-acpi input devices, and ACPI core netlink event
    interface, regardless of any module parameter.

    The module parameter was added to allow thinkpad-acpi to work with
    userspace that has been partially updated to use thinkpad-acpi input
    devices, but not the new ACPI core netlink event interface. To use this
    mode of hot key reporting, one has to specify the hotkey_report_mode=2
    module parameter.

    The thinkpad-acpi driver exports the value of hotkey_report_mode through
    sysfs, as well. thinkpad-acpi backports to older kernels, that do not
    support the new ACPI core netlink interface, have code to allow userspace
    to switch hotkey_report_mode at runtime through sysfs. This capability
    will not be provided in mainline thinkpad-acpi as it is not needed there.

  • 962ce8ca0   ACPI: don't duplicate input events on netlink ... Browse Code »

    The previous events patch added a netlink event for every
    user of the legacy /proc/acpi/event interface.

    However, some users of /proc/acpi/event are really input events,
    and they already report their events via the input layer.

    Introduce a new interface, acpi_bus_generate_netlink_event(),
    which is explicitly called by devices that want to repoprt
    events via netlink. This allows the input-like events
    to opt-out of generating netlink events. In summary:

    events that are sent via netlink:
    ac/battery/sbs
    thermal
    processor
    thinkpad_acpi dock/bay

    events that are sent via input layer:
    button
    video hotkey
    thinkpad_acpi hotkey
    asus_acpi/asus-laptop hotkey
    sonypi/sonylaptop

    The current kconfig help text was misleading users. Also, the default for
    an input-layer-optimized support caused way too many problems without
    up-to-date userspace in place.

    So, rework the help text, and change the default to N. Note that
    distributions are supposed to enable this option as soon as they update HAL
    to a version that handles the thinkpad-acpi new input layer interface.

    Fallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f. However, looking
    at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger
    at all (we never get to asus_led_exit() if registration fails) and
    if that registration fails, we actually leak stuff. IOW, it's worse
    than just replacing class_dev with dev in there - the tests themselves
    had been papering over the lousy cleanup logics.
