Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
This driver supports hardware monitoring for SoC's based on the ARM
|
||
|
|
System Control Processor (SCP) implementing the System Control
|
||
|
|
Processor Interface (SCPI). The following sensor types are supported
|
||
|
|
by the SCP -
|
||
|
|
|
||
|
|
* temperature
|
||
|
|
* voltage
|
||
|
|
* current
|
||
|
|
* power
|
||
|
|
|
||
|
|
The SCP interface provides an API to query the available sensors and
|
||
|
|
their values which are then exported to userspace by this driver.
|
||
|
|
|
||
|
|
Usage Notes
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The driver relies on device tree node to indicate the presence of SCPI
|
||
|
|
support in the kernel. See
|
||
|
|
Documentation/devicetree/bindings/arm/arm,scpi.txt for details of the
|
||
|
|
devicetree node.
