+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. Default to 1000 uOhm.
+- pga-gain: The gain value for the PGA function. This is 8, 4, 2 or 1. Default to 8.
+ The PGA gain affect the shunt voltage range.
+ The range will be equal to: pga-gain * 40mV.
+- bus-voltage-range: 32V or 16V, default to 32V.
+- nfactor: u8 array of three(TMP513) or two(TMP512) n-Factor value for each remote
+ temperature channel. Default to 0.
+ See datasheet Table 11 for n-Factor range list and value interpretation.
+
+Example:
+ tmp513@5c {
+ compatible = "ti,tmp513";
+ reg = <0x5C>;
+ shunt-resistor-uohm = <330000>;
+ bus-voltage-range = <32>;
+ pga-gain = <8>;
+ nfactor = [01 F3 00];
+ };

Since this is the devicetree documentation, it will need to be approved by
a devicetree maintainer. Wondering why that didn't happen, I just realized
what you did not copy the devicetree mailing list. Please do that when you
resend.
Note that they may require devicetree documentation in yaml format nowadays.
