From df922703574ebe9035045f7c7242a0ec0e11b980 Mon Sep 17 00:00:00 2001 From: Mike Looijmans Date: Fri, 15 Jan 2016 10:54:59 +0100 Subject: hwmon: Add LTC2990 sensor driver 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.
