+title: TMP513/512 system monitor sensor
+
+maintainers:
+ - Eric Tremblay <etremblay@distech-controls.com>
+
+description: |
+ The TMP512 (dual-channel) and TMP513 (triple-channel) are system monitors
+ that include remote sensors, a local temperature sensor, and a high-side
+ current shunt monitor. These system monitors have the capability of measuring
+ remote temperatures, on-chip temperatures, and system voltage/power/current
+ consumption.

+ shunt-resistor-micro-ohms:
+ description: |
+ If 0, the calibration process will be skipped and the current and power
+ measurement engine will not work. Temperature and voltage measurement
+ will continue to work. The shunt value also need to respect:
+ rshunt <= pga-gain * 40 * 1000 * 1000.
+ If not, it's not possible to compute a valid calibration value.
+ default: 1000
+
+ ti,pga-gain:
+ description: |
+ The gain value for the PGA function. This is 8, 4, 2 or 1.
+ The PGA gain affect the shunt voltage range.
+ The range will be equal to: pga-gain * 40mV
