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

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