    Introduce a core framework for run-time power management of I/O
    devices. Add device run-time PM fields to 'struct dev_pm_info'
    and device run-time PM callbacks to 'struct dev_pm_ops'. Introduce
    a run-time PM workqueue and define some device run-time PM helper
    functions at the core level. Document all these things.

    Special thanks to Alan Stern for his help with the design and
    multiple detailed reviews of the pereceding versions of this patch
    and to Magnus Damm for testing feedback.

  • a5766f11c   regulator: core - Rework machine API to remove string based functions. ... Browse Code »

    This improves the machine level API in order to configure
    regulator constraints and consumers as platform data and removes the
    old string based API that required several calls to set up each regulator.

    The intention is to create a struct regulator_init_data, populate
    it's fields with constraints, consumers devices, etc and then register
    the regulator device from board.c in the standard Linux way.

    e.g. regulator LDO2 (supplying codec and sim) platform data.

    /* regulator LDO2 consumer devices */
    static struct regulator_consumer_supply ldo2_consumers[] = {
    {
    .dev = &platform_audio_device.dev,
    .supply = "codec_avdd",
    },
    {
    .dev = &platform_sim_device.dev,
    .supply = "sim_vcc",
    }
    };

    /* regulator LDO2 constraints */
    static struct regulator_init_data ldo2_data = {
    .constraints = {
    .min_uV = 3300000,
    .max_uV = 3300000,
    .valid_modes_mask = REGULATOR_MODE_NORMAL,
    .apply_uV = 1,
    },
    .num_consumer_supplies = ARRAY_SIZE(ldo2_consumers),
    .consumer_supplies = ldo2_consumers,
    };

    /* machine regulator devices with thier consumers and constraints */
    static struct platform_device wm8350_regulator_devices[] = {
    {
    .name = "wm8350-regulator",
    .id = WM8350_LDO_2,
    .dev = {
    .platform_data = &ldo2_data,
    },
    },
    };

    Changes in detail:-

    o Removed all const char* regulator config functions in machine API.
    o Created new struct regulator_init_data to contain regulator
    machine configuration constraints and consmuers.
    o Changed set_supply(), set_machine_constraints(),
    set_consumer_device_supply() to remove their string identifier
    parameters. Also made them static and moved functions nearer top of
    core.c.
    o Removed no longer used inline func to_rdev()
    o Added regulator_get_init_drvdata() to retrieve init data.
    o Added struct device* as parameter to regulator_register().
    o Changed my email address.

  • 8e552c36d   power_supply: add CHARGE_COUNTER property and olpc_battery support for it ... Browse Code »

    This adds PROP_CHARGE_COUNTER to the power supply class (documenting it
    as well). The OLPC battery driver uses this for spitting out its ACR
    values (in uAh). We have some rounding errors (the data sheet claims
    416.7, the math actually works out to 416.666667, so we're forced to
    choose between overflows or precision loss. I chose precision loss,
    and stuck w/ data sheet values), but I don't think anyone will care
    that much.

  • 58aca2322   PM: Handle device registrations during suspend/resume ... Browse Code »

    Modify the PM core to protect its data structures, specifically the
    dpm_active list, from being corrupted if a child of the currently
    suspending device is registered concurrently with its ->suspend()
    callback. In that case, since the new device (the child) is added
    to dpm_active after its parent, the PM core will attempt to
    suspend it after the parent, which is wrong.

    Introduce a new member of struct dev_pm_info, called 'sleeping',
    and use it to check if the parent of the device being added to
    dpm_active has been suspended, in which case the device registration
    fails. Also, use 'sleeping' for checking if the ordering of devices
    on dpm_active is correct.

    Introduce variable 'all_sleeping' that will be set to 'true' once all
    devices have been suspended and make new device registrations fail
    until 'all_sleeping' is reset to 'false', in order to avoid having
    unsuspended devices around while the system is going into a sleep state.

    Remove pm_sleep_rwsem which is not necessary any more.

    Special thanks to Alan Stern for discussions and suggestions that
    lead to the creation of this patch.

  • 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).

  • 8f4ce8c32   serial: turn serial console suspend a boot rather than compile time option ... Browse Code »

    Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop
    the serial console from being suspended when the rest of the machine goes
    to sleep. This is incredibly useful for debugging power management-related
    things; however, having it as a compile-time option has proved to be
    incredibly inconvenient for us (OLPC). There are plenty of times that we
    want serial console to not suspend, but for the most part we'd like serial
    console to be suspended.

    This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel
    boot parameter (no_console_suspend). By default, the serial console will
    be suspended along with the rest of the system; by passing
    'no_console_suspend' to the kernel during boot, serial console will remain
    alive during suspend.

    For now, this is pretty serial console specific; further fixes could be
    applied to make this work for things like netconsole.

  • d5d8c5976   freezer: do not send signals to kernel threads ... Browse Code »

    The freezer should not send signals to kernel threads, since that may lead to
    subtle problems. In particular, commit
    b74d0deb968e1f85942f17080eace015ce3c332c has changed recalc_sigpending_tsk()
    so that it doesn't clear TIF_SIGPENDING. For this reason, if the freezer
    continues to send fake signals to kernel threads and the freezing of kernel
    threads fails, some of them may be running with TIF_SIGPENDING set forever.

    Accordingly, recalc_sigpending_tsk() shouldn't set the task's TIF_SIGPENDING
    flag if TIF_FREEZE is set.

    The name of 'struct pm_ops' suggests that it is related to the power
    management in general, but in fact it is only related to suspend.  Moreover,
    its name should indicate what this structure is used for, so it seems
    reasonable to change it to 'struct platform_suspend_ops'.  In that case, the
    name of the global variable of this type used by the PM core and the names of
    related functions should be changed accordingly.
