  • c8ac32e47   hwmon: (lm70) Add TI TMP121 support ... Browse Code »

    The Texas Instruments TMP121 is a SPI temperature sensor very similar
    to the LM70, with slightly higher resolution. This patch extends the
    LM70 driver to support the TMP121. The TMP123 differs in pin assign-
    ment.

    This fixes a byteswap bug in the LM70 temperature sensor driver,
    which was previously covered up by a converse bug in the driver
    for the LM70EVAL-LLP board (which is also fixed).

    Other fixes: doc updates, remove an annoying msleep(), and improve
    three-wire protocol handling.

    This driver implements support for the National Semiconductor LM70
    temperature sensor.

    The LM70 temperature sensor chip supports a single temperature sensor.
    It communicates with a host processor (or microcontroller) via an
    SPI/Microwire Bus interface.

    Communication with the LM70 is simple: when the temperature is to be sensed,
    the driver accesses the LM70 using SPI communication: 16 SCLK cycles
    comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
    complement digital temperature (sent via the SIO line), is available in the
    driver for interpretation. This driver makes use of the kernel's in-core
    SPI support.
