  • 674870385   hwmon: use simple i2c probe function ... Browse Code »

    Many hwmon drivers don't use the id information provided by the old
    i2c probe function, and the remainder can easily be adapted to the new
    form ("probe_new") by calling i2c_match_id explicitly.

    This avoids scanning the identifier tables during probes.

    Drivers which didn't use the id are converted as-is; drivers which did
    are modified as follows:

    * if the information in i2c_client is sufficient, that's used instead
    (client->name);
    * anything else is handled by calling i2c_match_id() with the same
    level of error-handling (if any) as before.

    A few drivers aren't included in this patch because they have a
    different set of maintainers. They will be covered by other patches.

  • 0a6bf658c   hwmon: (ltc4215) make sysfs file match the alarm cause ... Browse Code »

    The ltc4215 driver used the chip's "power good" status bit to provide
    the power1_alarm file. This is wrong: the chip is really reporting the
    status of one of the monitored voltages.

    Change the sysfs file from power1_alarm to in2_min_alarm instead. This
    matches the voltage that the chip is raising an alarm for.

  • 2d2a7cff1   ltc4215/ltc4245: Discard obsolete detect methods ... Browse Code »

    There is no point in implementing a detect callback for the LTC4215
    and LTC4245, as these devices 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
    callbacks. This shrinks the binary module sizes by 36% and 46%,
    respectively.

  • b6b9d6960   hwmon: (ltc4215) Clear faults at startup ... Browse Code »

    When power is applied to the ltc4215 chip it sometimes reports spurious
    faults. The faults are not yet exposed via sysfs, however it may be useful
    for userspace to read the fault register directly with the i2cget command.
    Clear the fault register when the driver is installed so userspace doesn't
    have to worry about spurious fault indications.

  • 72f5de92e   hwmon: Add LTC4215 driver ... Browse Code »

    Add Linux support for the Linear Technology LTC4215 Hot Swap controller
    I2C monitoring interface.

    I have tested the driver with my board, and it appears to work fine. With
    the power supplies disabled, it reads 11.93V input, 1.93V output, no
    current and no power. With the supplies enabled, it reads 11.93V input,
    11.98V output, no current, no power. I'm not drawing any current at the
    moment, so this is reasonable. The value in the sense register never
    reads anything except 0, so I expect to get zero from the current and
    power calculations.

    I didn't attempt to support changing any of the chip's settings or
    enabling the FET. I'm not sure even how to do that and still fit within
    the hwmon framework. :)
