    Add support for new device: the TI bq34z100-G1, a Wide Range Fuel Gauge
    for Li-Ion, PbA, NiMH, and NiCd batteries. The device shares a lot with
    other models, although it has its own differences requiring new quirks.

    This patch was tested on a system equipped with NiMH batteries.

  • c1f73028f   power: supply: charger-manager: Update extcon functions ... Browse Code »

    In commit 830ae442202e ("extcon: Remove the deprecated extcon functions")
    the function extcon_register_interest became a no-op returning an error,
    leading to non-functional behaviour in charger-manager.

    Additionally, a translation table is needed between the text representation
    of the extcon cable names and their IDs is needed. In order to retain DT
    compatibility, TA and CHARGE-DOWNSTREAM are added as they were present up
    until commit 11eecf910bd8 ("extcon: Modify the id and name of external
    connector")

  • e132fc6bb   power: supply: charger-manager: Make decisions focussed on battery status ... Browse Code »

    cm_monitor(), where charging management starts, checks various charging
    condition sequentially to decide next charging operation. However, as it
    follows sequential process, cascaded if statements, it does some
    jobs which have already done in the previous stage. This results in a
    delay in decision making. Moreover, starting point of charging is spread
    all around which makes maintain code and debugging difficult.

    Both of the problems mentioned above become clean if it manages battery
    charging focusing on battery status not following sequential condition
    checking. Now, cm_monitor() moves battery state diagram and does the
    optimal operation for current state. As a result, it reduces whole
    monitoring time almost in half.

    cm_notify_event() was introduced to get an event associated with the
    battery status externally (ie in board files), but no one ever used it.
    Moreover it makes charger manager driver more complicated. Drop the

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 67bd22c09   power: supply: bq27xxx: move platform driver code into bq27xxx_battery_hdq.c ... Browse Code »

    When the BQ27xxx driver was originally written the w1 subsystem only
    allowed device drivers for w1 attached devices to live in the w1
    subsystem. Kernel driver subsystems expect that the driver for a device
    live in the directory of the subsystem for which it implements
    functionality, not in the directory of the bus that it is attached. To
    work around this, the BQ27xxx driver was implemented as a platform device
    driver and the interface driver would instantiate this device from within
    the w1 directory, then pass a w1 read callback as platform data.

    As we can now have the w1 interface driver in the power/supply directory
    (like we do already with the i2c interface driver) we can remove this
    middle-layer platform driver.

    Userspace prefers the driver having a status property over having to guess
    itself. Specifically this will properly make the GNOME3 UI (and likely
    others) properly show discharging / charging / full status, instead
    of always showing discharging as status.

    Note that in the case there is no charger driver supplying the max17042,
    then a status of unknown will get returned. At least upower treats
    this the same as not having a status attribute, so in this case nothing
    changes from a userspace pov.
