  • 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.

  • 5c2f0dd57   hwmon: (mcp3021) use permission-specific DEVICE_ATTR variants ... Browse Code »

    Use DEVICE_ATTR_RO for read-only attributes. This simplifies the source
    code, improves readbility, and reduces the chance of inconsistencies.

    The conversion was done automatically using coccinelle. It was validated
    by compiling both the old and the new source code and comparing its text,
    data, and bss size.

  • 347d7e45b   hwmon: (mcp3021) Fix broken output scaling ... Browse Code »

    The mcp3021 scaling code is dividing the VDD (full-scale) value in
    millivolts by the A2D resolution to obtain the scaling factor. When VDD
    is 3300mV (the standard value) and the resolution is 12-bit (4096
    divisions), the result is a scale factor of 3300/4096, which is always
    one. Effectively, the raw A2D reading is always being returned because
    no scaling is applied.

    This patch fixes the issue and simplifies the register-to-volts
    calculation, removing the unneeded "output_scale" struct member.

  • 5510e62a6   hwmon: Add MCP3021 ADC driver ... Browse Code »

    Add I2C driver for MCP3021 that is an ADC chip from Microchip.
    The MCP3021 is a successive approximation A/D converter (ADC)
    with 10-bit resolution.
    The driver export the value of Vin to sysfs, the voltage unit is
    mV. Through the sysfs interface, lm-sensors tool can also display
    Vin voltage.
