  • GX20MH01 device shares family number 0x28 with DS18B20. The device
    is generally compatible with DS18B20. Added are the lowest 2^-5, 2^-6
    temperature bits in Config register; R2 bit in Config register
    enabling 13 and 14 bit resolutions. It is powered up in 14 bit mode.

  • The conversion time of common DS18B20 clones deviates from
    datasheet specs. Allow adjustment and automatic measure of the
    conversion time.

    Add 'conv_time' sysfs attribute:
    *read*: Current conversion time in milliseconds.
    *write*:
    '0': Set default conversion time.
    '1': Measure and set the conversion time. Make a
    single temperature conversion, poll and measure
    an actual value. Measured value is increased
    by 20% for temperature drift. A new conversion
    time is returned by reading the same attribute.
    other positive value:
    Set the conversion time in milliseconds.

    The setting is active until a resolution change. Then it is reset to
    default conversion time for a new resolution.

    Add 'features' sysfs attribute to control optional driver settings
    per device. Bit masks to read/write (logical OR):
    1: Enable check for conversion success. If byte 6 of
    scratchpad memory is 0xC after conversion, and
    temperature reads 85.00 (powerup value) or 127.94
    (insufficient power) - return a conversion error.

    2: Enable poll for conversion completion. Generate read cycles
    after the conversion start and wait for 1's. In parasite
    power mode this feature is not available.

    There are some clones of DS18B20 with fixed 12 bit resolution. Make the
    driver verify the resolution by reading back the device after resolution
    change.

  • Adding bulk read support:
    Sending a 'trigger' command in the dedicated sysfs entry of bus master
    device send a conversion command for all the slaves on the bus. The sysfs
    entry is added as soon as at least one device supporting this feature
    is detected on the bus.

    The behavior of the sysfs reading temperature on the device is as follow:
    * If no bulk read pending, trigger a conversion on the device, wait for
    the conversion to be done, read the temperature in device RAM
    * If a bulk read has been trigger, access directly the device RAM
    This behavior is the same on the 2 sysfs entries ('temperature' and
    'w1_slave').

    Reading the therm_bulk_read sysfs give the status of bulk operations:
    * '-1': conversion in progress on at least 1 sensor
    * '1': conversion complete but at least one sensor has not been read yet
    * '0': no bulk operation. Reading temperature on ecah device will trigger
    a conversion

    As not all devices support bulk read feature, it has been added in device
    family structure.

    The attribute is set at master level as soon as a supporting device is
    discover. It is removed when the last supported device leave the bus.
    The count of supported device is kept with the static counter
    bulk_read_device_counter.

    A strong pull up is apply on the line if at least one device required it.
    The duration of the pull up is the max time required by a device on the
    line, which depends on the resolution settings of each device. The strong
    pull up could be adjust with the a module parameter.

    Updating documentation in Documentation/ABI/testing/sysfs-driver-w1_therm
    and Documentation/w1/slaves/w1_therm.rst accordingly.

  • This is a respin with a wider audience (all that get_maintainer returned)
    and I know this spams a *lot* of people. Not sure what would be the correct
    way, so my apologies for ruining your inbox.

    The 00-INDEX files are supposed to give a summary of all files present
    in a directory, but these files are horribly out of date and their
    usefulness is brought into question. Often a simple "ls" would reveal
    the same information as the filenames are generally quite descriptive as
    a short introduction to what the file covers (it should not surprise
    anyone what Documentation/sched/sched-design-CFS.txt covers)

    A few years back it was mentioned that these files were no longer really
    needed, and they have since then grown further out of date, so perhaps
    it is time to just throw them out.

    A short status yields the following _outdated_ 00-INDEX files, first
    counter is files listed in 00-INDEX but missing in the directory, last
    is files present but not listed in 00-INDEX.

    List of outdated 00-INDEX:
    Documentation: (4/10)
    Documentation/sysctl: (0/1)
    Documentation/timers: (1/0)
    Documentation/blockdev: (3/1)
    Documentation/w1/slaves: (0/1)
    Documentation/locking: (0/1)
    Documentation/devicetree: (0/5)
    Documentation/power: (1/1)
    Documentation/powerpc: (0/5)
    Documentation/arm: (1/0)
    Documentation/x86: (0/9)
    Documentation/x86/x86_64: (1/1)
    Documentation/scsi: (4/4)
    Documentation/filesystems: (2/9)
    Documentation/filesystems/nfs: (0/2)
    Documentation/cgroup-v1: (0/2)
    Documentation/kbuild: (0/4)
    Documentation/spi: (1/0)
    Documentation/virtual/kvm: (1/0)
    Documentation/scheduler: (0/2)
    Documentation/fb: (0/1)
    Documentation/block: (0/1)
    Documentation/networking: (6/37)
    Documentation/vm: (1/3)

    Then there are 364 subdirectories in Documentation/ with several files that
    are missing 00-INDEX alltogether (and another 120 with a single file and no
    00-INDEX).

    I don't really have an opinion to whether or not we /should/ have 00-INDEX,
    but the above 00-INDEX should either be removed or be kept up to date. If
    we should keep the files, I can try to keep them updated, but I rather not
    if we just want to delete them anyway.

    As a starting point, remove all index-files and references to 00-INDEX and
    see where the discussion is going.

  • Onewire devices has 6 byte long unique serial numbers, 1 byte family
    code and 1 byte CRC. Linux sysfs presents the device folder in the
    form of familyID-deviceID, so CRC is not shown. The consequence is
    that the device serial number is always a 12 long hex-string, but
    doc says 13 in one place. This is corrected by this change.

  • The w1 master driver includes a complete open drain emulation
    reimplementation among other things.

    This converts the driver and all board files using it to use
    GPIO descriptors associated with the device to look up the
    GPIO wire, as well ass the optional pull-up GPIO line.

    When probed from the device tree, the driver will just pick
    descriptors and use them right off. For the two board files
    in the kernel, we add descriptor lookups so we do not need
    to keep any old platform data handling around for the GPIO
    lines.

    As the platform data is also a state container for this driver,
    we augment it to contain the GPIO descriptors.

    w1_gpio_write_bit_dir() and w1_gpio_write_bit_val() are gone
    since this pair was a reimplementation of open drain emulation
    which is now handled by gpiolib.

    The special "linux,open-drain" flag is a bit of mishap here:
    it has the same semantic as the same flags in I2C: it means
    that something in the platform is setting up the line as
    open drain behind our back. We handle this the same way as
    in I2C.

    To drive the pull-up, we need to bypass open drain emulation
    in gpiolib for the line, and this is done by driving it high
    using gpiod_set_raw_value() which has been augmented to have
    the semantic of overriding the open drain emulation.

    We also augment the documentation to reflect the way to pass
    GPIO descriptors from the machine.

  • This patch provides support for the DS28EA00 digital thermometer.

    The DS28EA00 provides an additional two pins for implementing a sequence
    detection algorithm. This feature allows you to determine the physical
    location of the chip in the 1-wire bus without needing pre-existing
    knowledge of the bus ordering. Support is provided through the sysfs
    w1_seq file. The file will contain a single line with an integer value
    representing the device index in the bus starting at 0.

  • Some preliminary work at making use of this driver led me to implement
    CRC-16 checks on read and write to deal with the occasional glitchiness of
    the 1-Wire bus. The revised driver (attached) returns an I/O error if the
    CRC check fails. When reading the chip's state, either you get a valid
    indication or you get an I/O error. When changing its state, either the
    change is successful or an I/O error is returned.

  • Applications can submit a set of commands in one packet to the kernel,
    and in some cases it is required such as reading the temperature
    sensor results. This adds an option W1_CN_BUNDLE to the flags of
    cn_msg to request the kernel to reply in one packet for efficiency.

    The cn_msg flags now check for unknown flag values and return an error
    if one is seen. See "Proper handling of unknown flags in system
    calls" http://lwn.net/Articles/588444/

    This corrects the ack values returned as per the protocol standard,
    namely the original ack for status messages and seq + 1 for all others
    such as the data returned from a read.

    Some of the common variable names have been standardized as follows.
    struct cn_msg *cn
    struct w1_netlink_msg *msg
    struct w1_netlink_cmd *cmd
    struct w1_master *dev

    When an argument and a function scope variable would collide, add req_
    to the argument.

  • The hardware search was failing without the COMM_RST flag. Enabled
    the flag and rewrote the function to handle more than one buffer of
    results and to continuing where the search left off. Remove hardware
    search note from the limitations now that it works. The "w1: ds2490
    USB setup fixes" change went from 23.16 seconds to about 3 seconds,
    this takes the time for the search down to .307346 seconds.

  • This is a 1-wire/w1 DS2423 slave driver for reading the values from all 4
    counters available DS2423 devices by using standard w1_slave file. In
    ds2423 the counters are tied to ram pages 12-15 in and each of those
    ram-pages. Each of these counter values (and asoociated ram page values)
    are represented as a own line in w1_slave file. Driver has been tested on
    mips and x86.

    usage example:
    cat /sys/bus/w1/devices/1d-00000009b964/w1_slave

  • Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • There is no point in implementing a detect callback for the DS2482, as
    this device can't be detected. It was there solely to handle "force"
    module parameters to instantiate devices, but now we have a better sysfs
    interface that can do the same.

    So we can get rid of the ugly module parameters and the detect callback.
    This shrinks the binary module size by 21%.
