A voltage rail produced by a regulator.
Voltage regulators produce one or more rails. Each rail typically provides a different output voltage level, such as 1.1V.
On a PMBus regulator with multiple rails, the current rail is selected using the PAGE command. Subsequent PMBus commands are sent to that PAGE/rail.
| Name | Required | Type | Description |
|---|---|---|---|
| comments | no | array of strings | One or more comment lines describing this rail. |
| id | yes | string | Unique ID for this rail. Can only contain letters (A-Z, a-z), numbers (0-9), and underscore (_). |
| configuration | no | configuration | Specifies configuration changes that should be applied to this rail. These changes usually override hardware default settings. The configuration changes are applied during the boot before regulators are enabled. |
| sensor_monitoring | no | sensor_monitoring | Specifies how to read the sensors for this rail. |
