1Kernel driver scpi-hwmon 2======================== 3 4Supported chips: 5 6 * Chips based on ARM System Control Processor Interface 7 8 Addresses scanned: - 9 10 Datasheet: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0922b/index.html 11 12Author: Punit Agrawal <punit.agrawal@arm.com> 13 14Description 15----------- 16 17This driver supports hardware monitoring for SoC's based on the ARM 18System Control Processor (SCP) implementing the System Control 19Processor Interface (SCPI). The following sensor types are supported 20by the SCP: 21 22 * temperature 23 * voltage 24 * current 25 * power 26 27The SCP interface provides an API to query the available sensors and 28their values which are then exported to userspace by this driver. 29 30Usage Notes 31----------- 32 33The driver relies on device tree node to indicate the presence of SCPI 34support in the kernel. See 35Documentation/devicetree/bindings/firmware/arm,scpi.yaml for details of the 36devicetree node.
