  • I power management document, Documentation/power/pci.txt, is
    outdated and partially inaccurate. It also is missing some important
    information about the power management of PCI device. Rewrite it to
    make it more up to date and more complete.

  • This patch changes the string based list management to a handle base
    implementation to help with the hot path use of pm-qos, it also renames
    much of the API to use "request" as opposed to "requirement" that was
    used in the initial implementation. I did this because request more
    accurately represents what it actually does.

    Also, I added a string based ABI for users wanting to use a string
    interface. So if the user writes 0xDDDDDDDD formatted hex it will be
    accepted by the interface. (someone asked me for it and I don't think
    it hurts anything.)

    This patch updates some documentation input I got from Randy.

  • There are subsystems whose power management callbacks only need to
    invoke the callbacks provided by device drivers. Still, their system
    sleep PM callbacks should play well with the runtime PM callbacks,
    so that devices suspended at run time can be left in that state for
    a system sleep transition.

    Provide a set of generic PM callbacks for such subsystems and
    define convenience macros for populating dev_pm_ops structures.

  • The power.runtime_auto device flag and the helper functions

  • The power management of some devices is handled through device types
    and device classes rather than through bus types. Since these
    devices may also benefit from using the run-time power management
    core, extend it so that the device type and device class run-time PM
    callbacks can be taken into consideration by it if the bus type
    callback is not defined.

    Update the run-time PM core documentation to reflect this change.

  • 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.

  • 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.
