*	hwmon: (ltc2990) support all measurement modes	Tom Levens	2018-05-21	1	-28/+168
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Updated version of the ltc2990 driver which supports all measurement modes (current, voltage, temperature) available in the chip. If devicetree is used, the mode must be specified with the property "lltc,meas-mode". The format and possible values of the property are described in the binding. If devicetree is not used, the mode of the chip will not be configured. Unless the chip is configured by another source, only the internal temperature and supply voltage will be measured.

*	hwmon: (ltc2990) Fix incorrect conversion of negative temperatures	Tom Levens	2018-05-21	1	-14/+4
\| \| \| \| \| \| \| \| \| \|	Fix incorrect conversion of negative temperatures by using sign_extend32() instead of a home-grown conversion function.

*	hwmon: Add LTC2990 sensor driver	Mike Looijmans	2016-03-05	1	-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.
