+[1] readpath has multiple options:
+* If it has "/xyz/openbmc_project/extsensors/" in it, it's an EXTERNAL or
+ host-provided sensor.
+* If it has "/xyz/openbmc_project/" in it, it's a sensor whose value is
+ received passively over dbus.
+* If it has "/sys/" in it, it's a sensor read directly from sysfs.

+[2]
+* This can be left blank if the sensor is read-only.
+* If it has "/sys/" in it, it's a sensor written to sysfs.
+ * If min and max are non-zero, it'll convert the value to within the range.
+ and output that modified value. So, if it receives a value of .90 and min
+ is 0, and max is 255, it'll convert that to a value of 229.5 that is then
+ cast to int64_t.
