    hwmon: Add LTC2990 sensor driver · df922703
    Mike Looijmans authored
    This adds support for the Linear Technology LTC2990  I2C System Monitor.
    The LTC2990 supports a combination of voltage, current and temperature
    monitoring. This driver currently only supports reading two currents
    by measuring two differential voltages across series resistors, in
    addition to the Vcc supply voltage and internal temperature.
    This is sufficient to support the Topic Miami SOM which uses this chip
    to monitor the currents flowing into the FPGA and the CPU parts.
