| 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. |
