2016-03-05hwmon: Add LTC2990 sensor driverMike Looijmans1-0/+161
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.
