  • f37079e9e   hwmon: (jc42) Fix name to have no illegal characters ... Browse Code »

    [ Upstream commit c843b382e61b5f28a3d917712c69a344f632387c ]

    The jc42 driver passes I2C client's name as hwmon device name. In case
    of device tree probed devices this ends up being part of the compatible
    string, "jc-42.4-temp". This name contains hyphens and the hwmon core
    doesn't like this:

    jc42 2-0018: hwmon: 'jc-42.4-temp' is not a valid name attribute, please fix

    This changes the name to "jc42" which doesn't have any illegal
    characters.

  • 1eade10fe   hwmon: (jc42) Use HWMON_CHANNEL_INFO macro ... Browse Code »

    The HWMON_CHANNEL_INFO macro simplifies the code, reduces the likelihood
    of errors, and makes the code easier to read.

    The conversion was done automatically with coccinelle. The semantic patch
    used to make this change is as follows.

    This patch does not introduce functional changes. Many thanks to
    Julia Lawall for providing the semantic patch.

  • 68615eb01   hwmon: (jc42) optionally try to disable the SMBUS timeout ... Browse Code »

    With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
    is not always capable of avoiding the 25-35 ms timeout as specified by
    the SMBUS protocol. This may cause silent corruption of the last bit of
    any transfer, e.g. a one is read instead of a zero if the sensor chip
    times out. This also affects the eeprom half of the nxp-se97 chip, where
    this silent corruption was originally noticed. Other I2C adapters probably
    suffer similar issues, e.g. bit-banging comes to mind as risky...

    The SMBUS register in the nxp chip is not a standard Jedec register, but
    it is not special to the nxp chips either, at least the atmel chips
    have the same mechanism. Therefore, do not special case this on the
    manufacturer, it is opt-in via the device property anyway.

  • eacc48ce3   hwmon: (jc42) Add I2C_CLASS_HWMON to detection class ... Browse Code »

    In 2011, commit 774466add7c ("hwmon: (jc42) Change detection class")
    changed the detection class of these chips to I2C_CLASS_SPD based
    on this premise: "makes more sense because these chips always live on
    memory modules"

    Today these chips have applications beyond memory modules. Examples are
    JC42.4 compatible chips such as MCP9804 and MCP9808, but also MCP9805,
    which is marked as JC42.4 compliant and suggested for use not only for
    DIMMS, but also as generic temperature sensor.

    Add I2C_CLASS_HWMON as an additional detection class to allow detection
    by hwmon class i2c adapters.

  • 0ea2f1db8   hwmon: (jc42) Add support for additional IDT temperature sensors ... Browse Code »

    TS3000GB0 has a new device ID (0x2913). Since IDT's datasheets suggest
    that the upper 8 bit of the device ID reflect the chip ID and the lower
    8 bit reflect the version number, modify the code to accept all chips
    with ID 0x29xx.

    Also add support for TS3001 and TSE2004.

    Some of the datasheets for older chips are no longer available from
    the IDT web site, so replace explicit links in the documentation with
    a generic note.

  • 5953e2761   hwmon: (jc42) Don't reset hysteresis on device removal ... Browse Code »

    Restoring the configuration register on device removal has the side
    effect of also resetting the hysteresis value. This is inconsistent as
    the other limits are not reset, only hysteresis. So, following the
    principle of least surprise, preserve the hysteresis value when
    restoring the configuration register.

  • 2c6315da6   hwmon: (jc42) do not allow writing to locked registers ... Browse Code »

    On systems where the temperature sensor is actually used, the BIOS is
    likely to have locked the alarm registers. In that case, all writes
    through the corresponding sysfs files would be silently ignored.

    To prevent this, detect the locks and make the affected sysfs files
    read-only.
