Description¶
This driver supports hardware monitoring for SoC’s based on the ARMSystem Control Processor (SCP) implementing the System ControlProcessor Interface (SCPI). The following sensor types are supportedby the SCP:
- temperature
- voltage
- current
- power
The SCP interface provides an API to query the available sensors andtheir values which are then exported to userspace by this driver.
Usage Notes¶
The driver relies on device tree node to indicate the presence of SCPIsupport in the kernel. SeeDocumentation/devicetree/bindings/arm/arm,scpi.txt for details of thedevicetree node.
