ServoMaster: Metadata: controller/maxservos
Definition
controller/maxservos property contains the maximum number of servos this controller is able to support.
Please note that this property may dynamically change value. For example, the USB QuadServo device may support one servo when bus powered, and the number of servos equal to number of connectors when self-powered.
Note
Even so, the QuadServo driver doesn't reflect this - it's
just an example.
