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