  8. Description
  9. -----------
  10. This driver supports hardware monitoring for SoC's based on the ARM
  11. System Control Processor (SCP) implementing the System Control
  12. Processor Interface (SCPI). The following sensor types are supported
  13. by the SCP:
  14. * temperature
  15. * voltage
  16. * current
  17. * power
  18. The SCP interface provides an API to query the available sensors and
  19. their values which are then exported to userspace by this driver.
  20. Usage Notes
  21. -----------
  22. The driver relies on device tree node to indicate the presence of SCPI
  23. support in the kernel. See
  24. Documentation/devicetree/bindings/arm/arm,scpi.txt for details of the
  25. devicetree node.
