These system monitors have the capability of measuring 17 remote temperatures, on-chip temperatures, and system voltage/power/current 18 consumption. 19 20 Datasheets: 21 https://www.ti.com/lit/gpn/tmp513 22 https://www.ti.com/lit/gpn/tmp512 23 24 25properties: 26 compatible: 27 enum: 28 - ti,tmp512 29 - ti,tmp513 30 31 reg: 32 maxItems: 1 33 34 shunt-resistor-micro-ohms: 35 description: | 36 If 0, the calibration process will be skipped and the current and power 37 measurement engine will not work.
