+TMP513 system monitor sensor
+-------------------------
+
+Require node properties:
+- compatible: one of
+ "ti,tmp512"
+ "ti,tmp513"
+- reg : the I2C address of the device. This is 0x5c, 0x5d, 0x5e, or 0x5f.
+
+Optional properties:
+- shunt-resistor-uohm : The shunt resistor value in uOhm. If 0, the
calibration process
+ will be skiped 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.
+- bus-voltage-range: 32V or 16V, default to 32V.
+- pga-gain: The gain value for the PGA function. This is 8, 4, 2 or 1. Default
to 8.
+- temp_2_nfactor: nFactor for remote channel 1. Value according to Table 11 in
datasheet.
+- temp_3_nfactor: nFactor for remote channel 2. Value according to Table 11 in
datasheet.
+- temp_4_nfactor: nFactor for remote channel 3. Value according to Table 11 in
datasheet,
+ TMP513 only.
+
+Example:
+ tmp513@5c {
+ compatible = "ti,tmp513";
+ reg = <0x5C>;
+ shunt-resistor-uohm = <330000>;
+ bus-voltage-range = <32>;
+ pga-gain = <8>;
+ temp_2_nfactor = <0x01>;
+ temp_3_nfactor = <0x02>;
+ temp_4_nfactor = <0x03>;
+ };
