| [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. |
