  • Usually PMIC's come with coulomb counting mechanism which can be
    used to implement a Fuel Gauginig solution in Software itself.
    One of key input to these SW Fuel Gauge solutioons is the boot up
    parameters like boot voltage and boot current.

    This patch adds the VOLTAGE_BOOT and CURRENT_BOOT power supply attributes
    to report bootup voltage and current.

    This patch also adds CALIBRATE power supply attribute which useful is
    for calibrating the battery/coulomb counter.

  • Pull ACPI and power management updates from Rafael Wysocki:
    "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
    commits) and system suspend/hibernation (9 commits).

    From the new code perspective, the ACPICA update brings ACPI 5.1 to
    the table, including a new device configuration object called _DSD
    (Device Specific Data) that will hopefully help us to operate device
    properties like Device Trees do (at least to some extent) and changes
    related to supporting ACPI on ARM.

    Apart from that we have hibernation changes making it use radix trees
    to store memory bitmaps which should speed up some operations carried
    out by it quite significantly. We also have some power management
    changes related to suspend-to-idle (the "freeze" sleep state) support
    and more preliminary changes needed to support ACPI on ARM (outside of
    ACPICA).

    The rest is fixes and cleanups pretty much everywhere.

    Specifics:

    - ACPICA update to upstream version 20140724. That includes ACPI 5.1
    material (support for the _CCA and _DSD predefined names, changes
    related to the DMAR and PCCT tables and ARM support among other
    things) and cleanups related to using ACPICA's header files. A
    major part of it is related to acpidump and the core code used by
    that utility. Changes from Bob Moore, David E Box, Lv Zheng,
    Sascha Wildner, Tomasz Nowicki, Hanjun Guo.

    - Radix trees for memory bitmaps used by the hibernation core from
    Joerg Roedel.

    - Support for waking up the system from suspend-to-idle (also known
    as the "freeze" sleep state) using ACPI-based PCI wakeup signaling
    (Rafael J Wysocki).

    - Fixes for issues related to ACPI button events (Rafael J Wysocki).

    - New device ID for an ACPI-enumerated device included into the
    Wildcat Point PCH from Jie Yang.

    - ACPI video updates related to backlight handling from Hans de Goede
    and Linus Torvalds.

    - Preliminary changes needed to support ACPI on ARM from Hanjun Guo
    and Graeme Gregory.

    - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui.

    - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros
    (Rafael J Wysocki).

    - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J
    Wysocki.

    - Cleanups and improvements related to system suspend from Lan
    Tianyu, Randy Dunlap and Rafael J Wysocki.

    - ACPI battery cleanup from Wei Yongjun.

    - cpufreq core fixes from Viresh Kumar.

    - Elimination of a deadband effect from the cpufreq ondemand governor
    and intel_pstate driver cleanups from Stratos Karafotis.

    - 350MHz CPU support for the powernow-k6 cpufreq driver from Mikulas
    Patocka.

    - Fix for the imx6 cpufreq driver from Anson Huang.

    - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep
    Tripathy and Mohammad Merajul Islam Molla.

    - Build fix for the big_little cpuidle driver from Sachin Kamat.

    - Configuration fix for the Operation Performance Points (OPP)
    framework from Mark Brown.

    - APM cleanup from Jean Delvare.

  • Add helper functions that allow regulator consumers to obtain low-level
    details about the regulator hardware, like the voltage selector register
    address and such. These details can be useful when configuring hardware
    or firmware that want to do low-level access to regulators, with no
    involvement from the kernel.

    The use-case for Tegra is a voltage-controlled oscillator clocksource
    which has control logic to change the supply voltage via I2C to achieve
    a desired output clock rate.

  • On some systems the platform doesn't support neither
    PM_SUSPEND_MEM nor PM_SUSPEND_STANDBY, so PM_SUSPEND_FREEZE is the
    only available system sleep state. However, some user space frameworks
    only use the "mem" and (sometimes) "standby" sleep state labels, so
    the users of those systems need to modify user space in order to be
    able to use system suspend at all and that is not always possible.

    For this reason, add a new kernel command line argument,
    relative_sleep_states, allowing the users of those systems to change
    the way in which the kernel assigns labels to system sleep states.
    Namely, for relative_sleep_states=1, the "mem", "standby" and "freeze"
    labels will enumerate the available system sleem states from the
    deepest to the shallowest, respectively, so that "mem" is always
    present in /sys/power/state and the other state strings may or may
    not be presend depending on what is supported by the platform.

    Update system sleep states documentation to reflect this change.

  • Rework dev_pm_qos_add_ancestor_request() so that device PM QoS type
    is passed to it as the third argument and make it support the
    DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type (in addition to
    DEV_PM_QOS_RESUME_LATENCY).

    That will allow the drivers of devices without latency tolerance
    hardware support to use their ancestors having it as proxies for
    their latency tolerance requirements.

    Signed-off-by: Rafael J. Wysocki

  • Add a new latency tolerance device PM QoS type to be use for
    specifying active state (RPM_ACTIVE) memory access (DMA) latency
    tolerance requirements for devices. It may be used to prevent
    hardware from choosing overly aggressive energy-saving operation
    modes (causing too much latency to appear) for the whole platform.

    This feature reqiures hardware support, so it only will be
    available for devices having a new .set_latency_tolerance()
    callback in struct dev_pm_info populated, in which case the
    routine pointed to by it should implement whatever is necessary
    to transfer the effective requirement value to the hardware.

    Whenever the effective latency tolerance changes for the device,
    its .set_latency_tolerance() callback will be executed and the
    effective value will be passed to it. If that value is negative,
    which means that the list of latency tolerance requirements for
    the device is empty, the callback is expected to switch the
    underlying hardware latency tolerance control mechanism to an
    autonomous mode if available. If that value is PM_QOS_LATENCY_ANY,
    in turn, and the hardware supports a special "no requirement"
    setting, the callback is expected to use it. That allows software
    to prevent the hardware from automatically updating the device's
    latency tolerance in response to its power state changes (e.g. during
    transitions from D3cold to D0), which generally may be done in the
    autonomous latency tolerance control mode.

    If .set_latency_tolerance() is present for the device, a new
    pm_qos_latency_tolerance_us attribute will be present in the
    devivce's power directory in sysfs. Then, user space can use
    that attribute to specify its latency tolerance requirement for
    the device, if any. Writing "any" to it means "no requirement, but
    do not let the hardware control latency tolerance" and writing
    "auto" to it allows the hardware to be switched to the autonomous
    mode if there are no other requirements from the kernel side in the
    device's list.

    This changeset includes a fix from Mika Westerberg.

  • Rename symbols, variables, functions and structure fields related do
    the resume latency device PM QoS type so that it is clear where they
    belong (in particular, to avoid confusion with the latency tolerance
    device PM QoS type introduced by a subsequent changeset).

    Update the PM QoS documentation to better reflect its current state.
