0014 Description
0015 -----------
0016
0017 This driver supports hardware monitoring for SoC's based on the ARM
0018 System Control Processor (SCP) implementing the System Control
0019 Processor Interface (SCPI). The following sensor types are supported
0020 by the SCP:
0021
0022 * temperature
0023 * voltage
0024 * current
0025 * power
0026
0027 The SCP interface provides an API to query the available sensors and
0028 their values which are then exported to userspace by this driver.

0030 Usage Notes
0031 -----------
0032
0033 The driver relies on device tree node to indicate the presence of SCPI
0034 support in the kernel. See
0035 Documentation/devicetree/bindings/firmware/arm,scpi.yaml for details of the
0036 devicetree node.
